Botany-Passive Transport Answers Essay Example for Free
Botany-Passive Transport Answers Essay Substances necessary for normal growth and development of plants must continually be transported into cells while metabolic wastes must be eliminated so that they wonââ¬â¢t accumulate inside the cells. For instance, water as well as mineral salts from the soil solution enter root cells while carbon dioxide and oxygen through tiny pores known as stomata in leaves and lenticels in stem. Excess oxygen not utilized during cell respiration as well as oxygen produced during photosynthesis is released to the atmosphere. In most cases, movement of these substances is along a concentration gradient, that is, from regions of greater concentration to regions of less concentration. Such type of transport is known as passive transport. Diffusion is a type of transport which is concerned with the movement of solute particles. Aside from concentration gradient, factors affecting the rate of diffusion include the temperature, size of diffusing molecules and presence of other molecules aside from the diffusing one. Osmosis, on the other hand, is another type of passive transport, which is involved in the movement of solvent (e.g. water) through a semi-permeable membrane. In osmosis, the presence of a differentially permeable membrane as well as differences in the concentration of the medium and the intracellular substance (i.e. cell sap) are factors to consider in determining the direction of water flow. (madel, dito gawa k ng visuals na puede,.. kung aong maisip mo di ko nga alam kung ano puede ndin ilgay â⬠¦. Ano kaya gagamitin ntin? Naka-acetate oh sa manila paper kaw n bhala..;) Now the walls of these cells are made of a stuff a bit like a really fine netting that will let water through but not salt (a partially permiable membrane). Now water and salt prefer being mixed together than seperated, and water will move through the cell wall towards whichever side is the saltiest, this is called osmosis. This means that because outside is saltier the water leaves the cells, so the cells empty, and like a half full bag of water, go all floppy so the whole lettuce leaf goes floppy Now if you put the leaf in fresh water there are more salts in the leaf than in the water, so water will move back into the cells making them blow up like balloons again and become all strong and rigid. So if you have some old limp Lettuce soaking it in water for a while for a while will make it go crisp again. -The leaf in the salt water would be dehydrated, as its internal osmotic pressure would make water from the leaf seep through the cellular membranes. -its osmosis. the cells in the leaf are permeable to water but not salt,so if you immerse the leaf in salt water the cell will absorb water trying to balance the osmotic pressure .if you put the leaf in fresh water the cells will dump water,the salt water will cause the cells to absorb too much water and they will burst,the fresh water leaf will dehydrate and wrinkle,i think i got it right but dont quote me. -Your talking about tonicity, the salt solution is hypertonic and would pull fluid from the plasmodesmata in the plant cellsthe plain water being relatively isotonic would have little loss of fluid depending on where you live in the country and if you used tap water or bottled. Its the same concept of cellular dehydration and water toxicity in human cells.

Public Opinion and Military Intervention
Public Opinion and Military Intervention For modern day states, especially democracies, the outcome of a military intervention is not just determined by the outcome on the battlefield but is also to a huge extent determined by the public opinion. The ââ¬Å"Vietnam syndromeâ⬠and the much recognized and debated topic regarding Vietnam as a political loss for the American is deeply interconnected with public opinion on the intervention. The aim of this paper is two understand how public opinion can ââ¬Ëmakeââ¬â¢ or ââ¬Ëbreakââ¬â¢ a military intervention. I will do this by firstly looking at how an activated opinion of the masses can dictate a governmentââ¬â¢s decision to intervene or not. Secondly, I will look at the casualty hypothesis wherein in a loss-averse public starts to view an intervention negatively as casualties start mounting up. For a long time public opinion was disregarded by academicians. Numerous communication models, like the Hypodermic Needle model or the Magic Bullet model, assumed that the public were mere consumers of information and that they lacked the element of rationality. As a result of this belief, which largely stemmed from the works of the Chicago School during the aftermath of the Second World War and the tragedy of Nazi Germany, it was believed that the public were vulnerable to any information being ââ¬Å"injectedâ⬠into them as a result of which their opinion was inconsequential. It was in this context that the idea, ââ¬Å"the President doesnââ¬â¢t follow public opinion, he leads itâ⬠emerged.[1] However, this dismissal attitude towards public opinion started to change as more and more research started to point towards the inherent rationality of the public and their ability to assimilate, analyze and impact policies, especially in the case of liberal and democratic societies.[2] Public opinion can in the words of V.O. Key be described as, ââ¬Å"those opinions held by private persons which the government find it prudent to heedâ⬠. The monumental impact of public opinion can be seen through the electorate decisions that the public makes. Therefore, democratic states need to pay attention to the demands of the public and are to huge extent dictated by the public opinion. In democratic states, the civil-military relations are such that the power of decision making pertaining to military intervention largely lies with the executive and the legislative, which in turn is affected by public opinion, and not with the military. The inter-connectedness of civil-military relations is not just limited to the decision of making a military intervention or not. It includes the use of military to promote democratic values in other countries and is also reflected in the ââ¬Å"cultural dimensions of strategy and policyâ⬠. In fact, post the Cold War era there has been an increased acceptance of the fact that culture, which includes identity, political culture in the â⬠¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦..of the structure of decision-making and public opinion, has increasingly become a factor in determining the course of todayââ¬â¢s complex and interconnected world.[3] Here it is important to note that every time the state makes the decision for or against a military intervention it does not proactively seek the publicââ¬â¢s opinion. This can be attributed to the fact that the public does not always have a well articulated opinion. However, this does not mean that the public does not have any opinion; it only means that the opinion is ââ¬Å"latentâ⬠. Latent public opinion refers to ââ¬Å"ingrained sets of values, criteria for judgement, attitudes, preferences, dislikes ââ¬â pictures in [the] head- that come into play when a relevant action, event, or proposal arisesâ⬠.[4] It shows that the public can many a times be considered as detached and/or uniformed. However, it is important to note that an unsophisticated public is not necessarily an irrational one.[5] Latent opinion when manifested can translate into active opinion. Therefore, it can be said that latent opinion has potential for expression- provided it is activated by some message or event. According to Mood theory that was articulated by Gabriel Almond, opinion becomes activated when two things happen simultaneously- a) events that directly threaten the normal conduct of affairs, and b) occurrence of assertive or self-confident moods among the public. Here the role of elite debate and media is crucial. A polarized public debate between key decision-makers which is covered by the media provides the public with signals that helps convert latent into activated opinion. The existence of latent public opinion is most visible in the case of foreign policy. Given the remoteness and the complexity of foreign policy the public is not very well informed about the foreign policy neither does it have a consolidated and concrete opinion on foreign policy matters. It is, particularly, difficult to assess Public opinion in the matters of Foreign policy. For instance, Public is unlikely to have refined views on issues of arms control and trade agreements as there are significant gaps in public knowledge on these issues. In the context of military intervention the public opinion is driven by two key factors- a) the relation between domestic and international politics, and b) the number of casualties sustained. ââ¬ËMaking or Breakingââ¬â¢ a military intervention Two- Level Game A governmentââ¬â¢s foreign policy and domestic policy have a deep impact on each other. That means a state does not intervene independent of domestic considerations. In fact, international negotiations between states, including the decision to militarily intervene, occur simultaneously with negotiations at the intra-national level. That means the executive needs to take into consideration the internal political environment while trying to deal and decide on an external policy. Economic, political and social factors all come into play while making such decisions; this is where public opinion, whether active or latent, also comes into play by either making a case for or case against military intervention. Japanese PTF Brazilian Domestic politics can have a direct bearing on international politics and vice versa. It is, therefore, important for policy makers to achieve domestic policy goals so as to maintainà international bargaining power. On the other hand, international negotiations must also be in tandem with domestic constraints. These premises are integral to Putnams Two-Level Game theory of international relations. At the national level, domestic groups often pressurise the government to adopt favorable policies to promote their interests. In turn the politicians seek power by forming coalitions among those groups. At the international level, national governments seek to maximize their own ability to satisfy domestic pressures, while minimizing the adverse consequences of foreign developments. Putnams theory involves two levels of interaction among players. It is important to noteà that the two-level game is incredibly complex; moves that are rational for a player at oneà stage may be injudicious for that same player at the other stage (Putnam 434). Toà simplify the game, it is broken down into two levels international and domestic. Atà Level I, the international level, bargaining between the negotiators leads to a tentative agreement. At this level of negotiations, the chief negotiator is the main negotiating force. The chief negotiator can be an individual, multiple persons, or single/multiple organizations depending on the situation. Level II, the domestic audience, constitutes separate discussions by supporters of the chiefà negotiator about whether to ratify the agreement. Level II can be characterized as a parliament, ratification vote, or any number of other instances requiring acceptance of the Level I agreement. The agreement formulated at Level I must be voted up or down by the constituents at Level II. Crucially, the important inter-relationship between the two levels is that any Level I agreement must be ratified by Level II (Putnam 436). Any modification of the agreement at Level II counts as a rejection of Level I and will require a re-opening of negotiations at Level I; final ratification must be voted either up or down by Level II (Putnam 437). II)à Causalities and Public Opinion In contemporary times the growing awareness and concern for human rights has led to the birth of a strong correlation between the number of casualties sustained and the public opinion about the military intervention. Sensitivity to causalities is believed to be the ââ¬Å"Achillesââ¬â¢ heel of modern-day democraciesâ⬠.[6] Favorable public opinion is an essential element to any administrationââ¬â¢s ability to prosecute war. This is because public opinion can constrain an administrationââ¬â¢s ability to carry out its foreign policy goals, especially if the boundaries of what is acceptable to the public are breached. If the war drags on, casualties are sustained, the principal foreign policy objectives are considered illegitimate or the public perceives that the policy is not being successful, it may ââ¬Å"push backâ⬠against or punish an administration by voting against it in the next election. This relationship is extremely strong and visible in the West as a result of, what Gerard Chaliand terms as, ââ¬Å"the Westââ¬â¢s inability to stomach the lossesâ⬠. With the establishment and recognition of human rights coupled with a demographic trend that suggests lower fertility and birth rates as compared to other parts of the world ensures that each and every life counts. These trends can be seen all throughout military interventions post the Second World War- ranging from the Vietnam and Korean War to Afghanistan and Iraq War, including the humanitarian interventions in Kosovo and Somalia. As a result of a loss-averse public, the decision to intervene is to large extent determined by the publicââ¬â¢s understanding of a) the possible swiftness of an attack, and b) the mounting cost of the intervention, especially in terms of the human lives. If the public is convinced that an intervention will be quick and will not protracted then it is more likely to create a favourable environment for the intervention amongst the people. However, if there are indicators that hint towards a long drawn-out conflict then the public opinion is bound to be largely against any such intervention. This can be seen during the Gulf War during Sr. Bushââ¬â¢s administration. Even though Americaââ¬â¢s ability to go for an ââ¬Ëall-outââ¬â¢ war in other countries had been largely crippled as a result of the ââ¬Å"Vietnam syndromeâ⬠, America was able to make a case of its intervention in the Gulf as a result of the swiftness of the attack. Additionally, given the heavy-dependence on aerial attacks the Americans and their allies were able to minimize personal losses which created a further favourable public opinion. Having said this, the public opinion can start to wither away as the public becomes aware of the mounting casualties. Over four thousand American casualties and over four years of conflict haveà had a significant influence on public support for the war in Iraq. The media response toà the climbing casualty rate, the November 2006 mid-term election results, and recent eliteà political rhetoric demanding withdrawal are important indicators that public support forà this conflict has deteriorated. A good example of this is the publicââ¬â¢s response to the Bush administrationââ¬â¢s Iraq policy in the November 2006 election. In fact, ââ¬Å"public opinion, the support and mobilization of which is required for sustaining an extended conflict, plays a critical role in resolution, especially whenà government preferences diverge from majority opinion.â⬠So important is public opinionà that it may be Americaââ¬â¢s Achilles Heel.

The Bubonic Plague: Crisis in Europe and Asia :: essays research papers
The Bubonic Plague: Crisis in Europe and Asia à à à à à There have been many natural disasters throughout history that have caused great damage physically, emotionally and mentally. The Bubonic Plague is considered by most to be the second worst disaster to have occurred throughout history. It all began in October 1348, when Genoese trading ships dropped anchor at the port of Messina, Sicily. The Ships had come from the Black Sea port of Kaffa (Truitt, 2001). The few of the crew members that were left alive carried with them a deadly disease so perilous that it would ultimately lead to death (Douglass, 1996). The sailors became infected when sick rats from Central Asia boarded their ships and the fleas that were feasting on the rats bit the sailors (Truitt, 2001). It was thought that the disease originated from the Far East and was spread along major trade routes. When it became clear that the ships from east carried the plague, Messina closed its port. The Ships were forced to seek harbor elsewhere around the Mediterr anean, which allowed the disease to spread very quickly (Truitt, 2001). This would be the beginning of a very traumatic event that would affect all aspects of European society. à à à à à The Bubonic Plague generated from a bacterium called Yersina pestis, which is a one-celled organism that multiplies rapidly once inside its host and produces three types of symptoms, depending on how it is spread (Aberth, 2000). The bacterium that leads to the Bubonic Plague usually is found in the bloodstream of wild black rats. It is then posed to humans by fleas that feed on the blood of rats and then bite humans, in which the bacterium is passed into the human bloodstream (Aberth, 2000). It takes between four and six days for a person infected with the Bubonic Plague to exhibit symptoms (Truitt, 2001). The most common symptom is swellings known as buboes (hence bubonic) that appear in the lymph glands near the initial flea bite (Douglass, 1996). The buboes are red at first, but later turn a dark purple or black they eventually bust open oozing blood and pus (Douglass, 1996). Other symptoms may include a high fever, often causing delirium, violent headaches, su bcutaneous bleeding, and damage to the nervous system caused from the bleeding, which leads to uncontrollable twitching and jerking (Aberth, 2000). There is also a foul odor that is associated with the excrement of blood, pus and sweat of those who are infected (Aberth, 2000).

Prejudice in Telephone Conversation and Dinner Guest-Me Essay -- Wole
Prejudice in Telephone Conversation and Dinner Guest-Me In the two poems, ââ¬ËTelephone Conversationââ¬â¢ and ââ¬ËDinner Guest-Me,ââ¬â¢ each poet uses their poetry as a means of confronting and challenging prejudice. In ââ¬ËTelephone Conversationââ¬â¢ by Wole Soyinka, a phone conversation takes place between an African man and a very artificial lady about renting out a room. When the lady finds out he is African she becomes very prejudiced and racist towards him. ââ¬ËDinner Guest-Meââ¬â¢ by Langston Hughes is about a black man going to a dinner party where he is the only coloured person there, like he is the ââ¬Ëtoken black.ââ¬â¢ Anger and a sense of humour are shown in both of the poems. In ââ¬ËTelephone Conversationââ¬â¢ the African man is angry at the ââ¬Å"peroxide blondâ⬠and is disgusted at her for being so rude and racist towards him, ââ¬Å"HOW DARK? ARE YOU LIGHT OR VERY DARK?â⬠The capital letters emphasises the loudness in her voice, whereas, in Langston Hughes poem the other dinner guest are not being prejudiced to the only black dinner guest directly. Although they would ask him ââ¬Å"the usual questions that come into white mind.â⬠Here they are set apart from him as a different race, ââ¬Å"to be part of a Problem on Park Avenue at eight is not so bad.â⬠Heââ¬â¢s angry because he is still part of the Negro Problem even though he is with elegant, upper-class people. Hughes is laughing at the white people complaining about not being black, ââ¬Å"Iââ¬â¢m so ashamed of being white,â⬠also at the democratic process and him self. He uses satirical humour at the dinner party by poking at establishment. He acknowledges that ââ¬Å"I know I am the Negro Problemâ⬠and is aware they have to be polite about him. Wole Soyinka uses sarcastic humour and makes fun of the landlady when he wr... ...ws plenty of anger from Wole Soyinka towards the artifical, white, public. Hughes also seems to be mad at the white populace and thoroughly benefits from poking fun at them. I think Soyinka is trying to make a point of the phony and vulgar individuals there are and draw everyoneââ¬â¢sââ¬â¢ attentions to them, Hughes is trying to make us realise just how obnoxious some can be to different races, likewise to Soyinka. I believe both poets succeeded, the poems did make me consider how prejudice many persons are. In conclusion I prefer ââ¬ËDinner Guest-Meââ¬â¢ by Langston Hughes because I enjoyed the satirical humour he used in his poem and how he made the ââ¬Ëtoken blackââ¬â¢ stand out from all the other guests. Although I think that both use their poetry well as a means of confronting and challenging prejudice that was around back in the 1900s when the two poems were written.
Custom Essays: Hamlet as an Accessory to Ophelias Suicide
Hamlet as an Accessory to Ophelia's Suicideà à à à à à à à William Shakespeare's character of Ophelia in Hamlet, suffers greatly, from the time she learns of her father Polonius' death, until her own mysterious death.à In Hamlet, Gertrude, Horatio and Claudius refer to her state, and conclude that she is crazy1[1].à Though there is some truth to their claim, Shakespeare created Ophelia as an overly- dramatic character, who is somewhat exaggerating her emotions to give an impression of madness.à Although their impression of Ophelia can be supported, evidence is not shown as much in her words, as it is shown in her actions.à Ophelia's songs seem like riddles and nonsense2[2], yet they are similar to the patterns of speech by Hamlet, revealing truths and true emotions, and at times sarcasm.à à However, Ophelia's whimsical, and child-like behavior is quite different than the prim, reserved Ophelia at the beginning of the play.à Still, this behavior is not consistent with theà sad words in her grief-lad en songs, nor is it consistent with a woman in grief rather Ophelia's physical behavior is the strongest evidence that Ophelia may exhibit signs of madness.à Hamlet's act to convince his insanity to all that knew him influenced Ophelia to perform following Hamlet's lead with à his feigned madness, eventually leading to the girl's suicide, thus implicating Hamlet in her death. à In act four, scene five; Gertrude and Horatio discuss Ophelia's worsening condition directly prior to her entrance.à They attribute the young girls' decline to her concern for her recently dead father.à Ophelia displays signs of being overly sensitive and volatile, which concerns Horatio: "Spurns enviously at straws, speaks things in doubt / That carry but... ... à Notes: 1[1] Hamlet, (4.5.3,5-10). 2[2] Hamlet, (4.5.7) 3[3] Hamlet, (4.5.6-7).à 4[4] Neely, Carol Thomas, "Document in Madness", University of Illinois, Shakespeare Criticism Yearbook 1991, Volume 19, pp 333-334. 5[5] Hamlet, (4.5.21).à 6[6] Hamlet, (4.5.29-32) 7[7]Hamlet, (2.2.186) 8[8] Turner, John, "Hamlet: The Court in Transition".à University College of Swansea, Shakespearean Criticism, Volume 16, Yearbook 1990, p. 253. 9[9] Neely, p. 333. 10[10] Hamlet, (4.5.47-54) 11[11] Neely, p. 333. 12[12] Hamlet, (4.5.55). 13[13] Neely, p. 333. 14[14] Hamlet, (4.5.159). 15[15] Hamlet, (4.5.176-186) 16[16] Persoon, James.

Diabetes Type II
Diabetes is a condition characterized by individuals having elevated levels of blood sugar resulting from the body not producing sufficient insulin or the body cells not effectively responding to the insulin already present in the body (Kilvert & Fox, 2007). Insulin, a hormone produced in the pancreases, enables the body cells to take up glucose and oxidizes it into energy (Zieve & Wexler, 2009). Lack of this glucose uptake by the body cells will result to the accumulation of glucose in the blood, a condition known as hyperglycemia (Kilvert & Fox, 2007).Hyperglycemia leads to a number of other serious complications. In type II diabetes also known as non-insulin-dependent diabetes mellitus (NIDDM) results from the body cells becoming resistant to insulin or the insulin that is produced in the body is insufficiency (Kilvert & Fox, 2007). The onset of diabetes type II can be characterized by individuals having general weakness, chronic fatigue, malaise and lethargy. Frequent urination i s not unusual and individuals often complain of excessive thirst.Excessive movements in the bowel and unexplained weight loss have been observed among individuals afflicted by the condition (Mayo Clinic, 2009). The individuals suffering from diabetes type II start having blurred vision caused by the alteration in the shape of the lens due to osmotic factors chiefly the elevated levels of blood glucose. Frequent thirst leads to the affected individual taking a lot of fluids. Diabetes type II is known to be a genetic disease although medical causes have been explained (Kilvert & Fox, 2007).There is an observation of an increased risk of developing diabetes type II in families where the parents have the disorder. A mutation in the gene known as the Amyloid Polypeptide gene lead to the early signs of the condition and makes the progress to a more severe diabetes type II condition possible (Kilvert & Fox, 2007). Apart from genetics, the condition can be caused by an alteration in the met abolism and deranged cell processes. Environmental factors have also been blamed to cause diabetes type II particularly some diets and weight (Zieve & Wexler, 2009).Some drugs have been identified to increase the risk of diabetes type II such as the thiazide diuretics, which inhibit the secretion of insulin because of the hypokalemic condition they cause. Thiazides also increase the insulin resistance due to elevated levels of mobilization of free fatty acids (Mayo Clinic, 2009). Other drug agents that can be blamed for drug induced hyperglycemia include beta blockers, somatropin, protease inhibitors, phenothiazines, flouroquinolones, corticosteroids, antipsychotics and calcium channel blockers. Treatment of Diabetes Type IIThe immediate objective of treating diabetes type II is to reduce the elevated levels of blood glucose while the long-term goal of diabetes treatment is the prevention of diabetes-related conditions, which arise after individuals have developed the complication. Diet and exercise remain the primary ways of managing diabetes (Ligaray & Isley, 2010). The afflicted individuals should be able to accurately test and record their levels of blood glucose. The knowledge on what to eat and what medications to use should be well known by people suffering from the disease. The patients should get important information from their doctors.Individuals with diabetes type II are recommended to eat at the same times every day and their meals should be consistent in terms of the type of foods they choose to eat (Ligaray & Isley, 2010). The adherence of the meal intervals and the type of foods eaten help prevent the increase or decrease in the levels of blood sugars. Individuals can plan their meals by eating the right quantity of foods, choosing healthy foods and eating the meals at the required time. Another aspect is the weight management. It has been observed that some people after cutting weight can stop taking medications even when they still have diabe tes.In extreme overweight individuals, bariatric surgery may be recommended. Gastric bypass surgery and laparoscopic gastric banding are some of the weight reduction procedures that can be recommended in the management of diabetes (Ligaray & Isley, 2010). For diabetics, regular physical exercise is imperative (Mayo Clinic, 2009). It has been observed that aerobic exercise carried out regularly can help reduce the levels of blood sugars without the need of any medication. Exercise help to burn any excess fats and calories and therefore individuals with diabetes can easily manage their weight through exercises.Blood pressure and blood flow, which may be seen as a problem in diabetes type II can be improved (Mayo Clinic, 2009). Exercise decreases the insulin resistance in body cells without necessarily having any body loss. The bodyââ¬â¢s energy level is also said to improve with exercise and the ability to handle stress as well as lowering of tension are some of the benefits of exe rcise. When all the options of exercise and diet have failed, individuals may opt for medications that are prescribed by physicians. The drugs acting against diabetes function to lower the blood sugar levels in a number of ways (Ligaray & Isley, 2010).Physicians may prescribe for patients more than one type of medication because of the different modes of action of the different agents used in diabetes management. The drugs are also prescribed along with insulin when it is required. The drugs used in diabetes treatment are either given intravenously or orally. For instance, biguanides sold as metformin is used to decrease the hepatic production of glucose (Mayo Clinic, 2009). The rationale of biguanides is to make the fat cells, hepatic cells and the muscle cells to absorb more glucose from the bloodstream hence lowering the total blood sugar levels.Alpha-glucosidase inhibitors are also important agents that lower the carbohydrate absorption from the digestive tract. This lowers the glucose levels especially after the meals. Sulfonylureas help in triggering the pancreases to produce more insulin and they are administered by oral route (Ligaray & Isley, 2010). Other agents used in diabetes management include the thiazolidinediones, pramlintide and exenatide and meglitinides. Insulin is only prescribes to patients who fail to respond to other methods of disease management such as diet monitoring, exercise and other medications (Mayo Clinic, 2009).In addition, insulin may be recommended for individuals who have poor reactions towards other medications used. Usually, insulin is injected under the skin by the use of an insulin pen device or a syringe. Insulin is never administered orally as proteolytic enzymes in the stomach may act on the hormone hence affecting the efficacy. In diabetes type II, the body cells fail to respond effectively to insulin even when it is present (Ligaray & Isley, 2010). This is typically seen in type II diabetes mellitus where the resist ance is cause by post-receptor derangements.Post-receptor effect implies that the insulin is sufficiently produced but the cells which should physiologically respond to the molecule have a problem recognizing the insulin (Ligaray & Isley, 2010). There is a general observation that the increased glucose production in the liver particularly in inappropriate times contributes to the inability of the body cells to respond to the ligand, insulin (Ligaray & Isley, 2010). This process, the conversion of glycogen to glucose affects the insulin level, which is important in hepatic function.The reduced insulin-dependent glucose transport especially in muscles and adipose tissues also contributes to the problem of diabetes type II. Similarly, there is an impaired function of beta-cells in the early phase of insulin release following the hyperglycemic stimuli. Diabetes type II is a condition which not only affects the regulation glucose levels but also other important body systems such as the i mmune system, renal function, reproductive system and cardiovascular system are largely affected (Kilvert & Fox, 2007). The immune system is hampered among the individuals suffering from diabetes type II.This can be seen in situations where diabetic individuals take a longer healing from the wounds and minor surgical incisions. The incidences of coronary artery complications as well as the arterial diseases are common among the individuals suffering from diabetes type II (Zieve & Wexler, 2009). Renal failure can be the most disturbing complication of diabetes type II where individuals may require dialysis for blood purification (Mayo Clinic, 2009). Diabetes type II has also been identified to be causing erectile dysfunction which can be a major problem in marriages.In general, diabetes type II is a problem which affects a number of body systems and leaves the affected individual and the family members and friends with a great burden. It is a condition of economic importance and effe ctive approach should be directed to its prevention and treatment. The social aspect of the patients and those close to them is affected. Although medications have been developed to manage the condition, effective treatments have not been developed, which can completely treat the problem. This calls for extensive research to come up with ways to manage diabetes type II.

I am a strong believer in the saying like father, like son goes with both genders, however, I do think that this is more a result of following example rather than a result genetics. It is common knowledge that not everyone is perfect, even heroes, and in realizing this I know.Although I wish to be like my mom in most ways I do not at all. This realization may be one of the most important things I have l earned, my mom has taught me to be firm in my decisions in life, not solely on the examples and actions of others but simply on what I gather and learn from the examples and actions of others. In other words, she has taught me not to follow blindly but to make my own decisions based on what I think is important. The things I have learned and continue to learn from my mom are continuous she has taught me all of the founding principles of my life and for that I am very thankful.
