The Advantures Of Huck. Fin Essay Example For Students

The Advantures Of Huck. Fin Essay Books are known for teaching lessons. In Huckleberry Finn, Mark Twain satirically presents the situation of how people of different color were treated unjustly, while at the same time amusing his readers. Isnt it ironic that the character that grows on you most is Jim, the black runaway slave, who society looks down upon most during the time period of this book? Jim is treated poorly as a slave and as a person. For one, he is separated from his parents and children amongst different slave owners. On top of this, he is about to be sold for $800 to another owner even more far away from his family, which leads to his escape. Despite these situations, he remains a loyal, loving, father-like figure, and most importantly, he remains a great friend to Huckleberry. We will write a custom essay on The Advantures Of Huck. Fin specifically for you for only $16.38 $13.9/page Order now Society, even today, often puts children down by saying that they do not contain values. Well, Huck closes the door to this statement. Whenever Huck is challenged to make a decision on impact concerning the safety of Jim, such as the incident when the men are looking for blacks, his heart always seems to pilot him to the direction of Jims benefit, even though almost all of the rest of society would object to his decisions during this period of time. You can also see Hucks distress and sorrow for the fact that Jim has to buy his family back in order to see them again. This absolutely breaks Hucks heart. Back in the 1800s, blacks were considered property, and whites were always the superior race. In Huckleberry Finn, Mark Twain purposely makes Jim the best character in the book, in that he is the most compassionate, caring, and most appreciated by Huck, the main character in the book. At the same time he makes Pap, the white dead-beat father of Huck, the most detested, disrespected, low down character of this book. Twain causes his readers to contemplate of how foolish it is that a person can be judged on his outside appearance, rather than who the individual is on the inside. In conclusion, the lesson to be taught by Mark Twain is that people often pre-judge others based on their exterior and not what counts on the interior. He does this satirically by making Jim an irresistibly lovable character because of how deep his feelings are, making the reader feel these insights as well. This is a lesson that can unquestionably be applied in todays world as well.

Pepsin Experiment

Pepsin Experiment Aim: To see how effectively the enzyme (pepsin) will work in different concentrates of acid. Also to determine if the enzyme becomes denatured.Prediction: Enzymes are proteins. The functions of an enzyme is determined by the shape of the protein. The arrangement of molecules on the enzyme produce an area known as the active site in which the specific substrate(s) will "fit". It recognises, confines and orients the substrates in a particular direction.Enzymes allow many chemical reactions to occur within the homeostasis constraints of a living system. Enzymes function as an organic catalysts. A catalyst is chemical involved in, but not changed by, a chemical reaction. Many enzymes function by lowering the activation energy in reactions. By bringing the reactants closer together, chemical bonds may be weaken and reactions will proceed faster than without a catalysts.Enzymes can act rapidly, as in the case of carbonic anhydrase, which causes the chemicals to react 107 times faster than without the enzymes present.English: Chemical reaction catalyzed by the lactas...Carbonic anhydrase speeds up the transfer of carbon dioxide from cells to the blood. There are over 2000 known enzymes, each of which are involved with one specific chemical reaction. Enzymes are substrate specific. The enzyme peptidase (which breaks peptide bonds in proteins) will not work on starch (which is broke down by human-produced amylase in the mouth).Increase in temperature will speed up the rate of non-enzyme mediated reactions, and so temperature increase speeds up the enzyme mediated reaction, but only to a certain point. When heated too much, enzymes become denatured, because they are proteins dependant on the shape. When/if the temperature drops, the enzyme regains its original shape. Concentration of substrate and product also controls the rate of the reaction, providing biofeedback mechanism.Changes in pH will also denature the enzyme, by changing the shape...
