In the play "Hamlet," written by William Shakespeare, there are several elements of tragedy that contribute to the overall tragic atmosphere and mood of the work. These elements include the tragic hero, the tragic flaw, the cause and effect chain of events, and the tragic resolution.

The tragic hero of "Hamlet" is, of course, the titular character himself. Hamlet is a prince who is grappling with the sudden death of his father, the King of Denmark, and the revelation that his uncle, Claudius, was responsible for the murder. Hamlet is torn between his desire for revenge and his sense of moral obligation, and this internal conflict is a key element of his tragic character.

One of the defining characteristics of a tragic hero is their tragic flaw, or the inherent quality or weakness that ultimately leads to their downfall. In the case of Hamlet, his tragic flaw is his indecision and procrastination. He spends much of the play debating and contemplation his actions, and this ultimately leads to the tragic resolution of the play.

The cause and effect chain of events in "Hamlet" is another key element of the tragedy. The chain of events begins with the murder of the King, which sets in motion a series of events that culminate in the tragic resolution of the play. The cause and effect chain is further complicated by the various characters' motivations and desires, which are often in conflict with one another.

Finally, the tragic resolution of "Hamlet" is the tragic ending of the play, in which many of the main characters, including Hamlet, die. This resolution is a result of the chain of events set in motion by the murder of the King, as well as the tragic flaws of the characters, particularly Hamlet's indecision and procrastination.

Overall, the elements of tragedy in "Hamlet" contribute to the overall tragic mood of the play and make it a classic work of tragedy in the tradition of Shakespearean drama.

Macromolecules, macronutrients

When testing for the vitamin C, small amounts of vitamin C was added to the iodine solution, this determines whether or not a redox reaction will take place to transfer vitamin C electrons to the iodine. Proteins Proteins are the polymers of amino acids. Explore the resources given and write a paragraph summarizing what are Carbohydrates, Proteins, and Lipidsand where to find them. University of California San Francisco. Water will also serve as a great way to compare color changes, since everything that looks the same as the water will be negative. The digestion process for carbohydrates starts in the mouth where an enzyme called salivary amylase begins to break down food starches into disaccharides. The monomer units of macromolecules are polar in nature, with their heads and tails with different physical and chemical properties.

A simple paper test was used evaluting lipid existence for each food. The tests performed were, iodine testing for Materials and Methods The experimental material and methods used to carry out this experiment is out lined in the Biol. The nutrition label tells you how many nutrients are in that amount of food. Free fatty acids are absorbed though the intestinal wall via diffusion to be transported around the body, or are taken up and incorporated into intestinal cells. L Tymoczko, L Stryer.

This result is because of the redox reaction that takes place between these two compounds. Pearson Custom Publishing, Boston, MA. Compare the test results of the snack taken from the scene of the crime to the residues found on each suspect. Biochemistry, 5 th ed. Macromolecules are identified in all the processed foods you eat, this information is given in the food labels, just like the one shown bellow. First is the break-down of the carbohydrates bread. The objective of this lab was to correctly identify which macromolecules the unknown solution was comprised of using various substances as experimental controls.

Our mouths chew food into smaller fragments while enzymes in our saliva start to chemically break down foods. They consist of monosaccharide sugars of varying chain lengths. This is used to detect the presence of lipids. Common foods that contain proteins are milk, eggs, meat and cheese. This short quiz does not count toward your grade in the class, and you can retake it an unlimited number of times.

This is the process of chewing it in your mouth. Once this food moves into the small intestine, a range of other enzymes trypsin, elastase, and chymotrypsin are released from the pancreas and start to reduce peptides into amino acids and di- and tri-peptides small chains of amino acids. Milligrams are very tiny — there are 1,000 milligrams in 1 gram. A positive result for proteins will show a color change from a blue to a light purple. Common foods that contain carbohydrates are potatoes and bread.

The protein solution did change color to violet-purple when tested with the Biuret test, resulting in a positive reaction. Our results confirmed our estimations of the foods' compounds. Learning experience 4 teaches the understanding of how to identify a small sample of Biomolecules within a wide variety of substances. Testing for Lipids, Proteins and Carbohydrates. The test that best shows the presence of lipids is the Sudan III test. Lipids come in different types, such as waxes, oils and certain vitamins.

This can be achieved by studying their chemical properties and structure. COLORIMETRIC DETERMINATION OF GLYCOGEN DISADVANTAGES OF THE IODINE METHOD. Abstract: We tested five common food items to determine which macromolecules were present. Another important part of the label is the number of calories that come from fat. The body begins breaking it down with salivary amylase. Gaithersburg, MD: Aspen Publishing, 1998.

Different types of monomers can combine in many configurations, giving rise to a diverse group of macromolecules. Our test showed this when our suspected solution exhibited this change in color to red. Focused Background Iodine test is the most common test for detecting the presence of starch. DETERMINATION OF SERUM PROTEINS BY MEANS OF THE BIURET REACTION. This is because fibre is indigestible and does not provide a source of energy. For further information about the breakdown and use of carbohydrates in the body, see How does the body break down protein? Emulsification break down fats into smaller globules so they can be more evenly distributed through the small intestine.

So if you look at it it makes this nice hexagon shape. While some of these compounds can be detected by taste tests, many cannot. Gastric acid also helps to partially break up proteins to allow pepsin better access. Certain carbohydrates are an important storage and transport form of energy in most organisms, including plants and animals. The water will be used as a control, to see if there are any false positive reactions during our experiment.
