In this lab, proper laboratory technique was implemented to have the experience in the lab. Furthermore, the unknown solution needed to be investigated, to determine the solution’s macromolecules. Three methods were comprised to determine the unknown, but a set of other solution was used to help as indicators to match the unknown solution’s results. It’s consisted of biuret, iodine and benedict solution. Iodine solution is used to determine if the source had starch or glycogen. If the source had glycogen consisted inside, there would be a reddish-brown precipitation occurring (Daniel Luzon Morris,1946). Iodine can also react with the starch, which could potentially create a The colour of the precipitate that forms a purple precipitate (J.M Bailey,W.J Whelan, 1960). The colour happens because of the iodine reacting with the glucose inside the starch. (J.M Bailey,W.J Whelan, 1960). Biuret test is to detect protein is extremely small, it is supposedly around the value of 0.5mg/ml. (Crowe,2014). This means 0.5x M of protein, the biuret solution would not change the if any solutions consisted less than the face value will not be detected 0.5x. When protein is detected, the solution would turn purple (Banks, 2016). Benedict solution is another method used to determine the unknown and if the solution The benedict solution is sensitive to the sugar and is able to detect and produce a shade of yellow, green or red (Stanley Benedict,1909).

Analysis Of The Movie Holden Caulfield - 1335 Words

When his flashback begins, Holden Caulfield has gotten kicked out of Pencey Prep School and he goes to New York early before his parents find out he had been kicked out. He wants to be like an adult but feels like everyone around him is a â€Å"phony,† because of his internal struggles that result from things like his brother Allie’s death and his interest in Jane Gallagher. Holden begins the novel when he is seventeen by saying that he is not going to tell his whole backstory, and he is just going to state what happened to him last Christmas around 1949, before he got â€Å"run-down† and was sent to what seems to be a mental institution to â€Å"take it easy† (Salinger 1). He says that his brother, D.B., would drive him home from the institution†¦show more content†¦Spencer tries to lecture Holden about his future and how he should apply himself, but Holden just says that he does not feel much concern towards his future. The discussion does not help Holden’s attitude, and he makes up an excuse to leave the old man’s house. Holden stays in the dorms in the Ossenburger Memorial Wing, named after a rich donor, with other juniors and seniors. He puts on a red hunting hat he bought that morning and sits down to read a book. He had only read a few pages when Robert Ackley, who stayed in the adjacent dorm, barged in. Ackley was a peculiar senior that did not go out much, hated Holden’s roommate, and was very unhygienic. Ackley walks around the room pestering Holden by picking up personal belongings and cutting his nails all over the floor. Ward Stradlater, Holden’s roommate walks in and asks to borrow Holden’s coat. Holden goes with Stradlater to the bathroom where Stradlater asks Holden to write a composition for him while he is out on a date. Holden inquires about Stradlater s date, and is shocked to find out that it is Jane Gallagher, an old friend of his. He asks Stradlater many questions about Jane and remains occupied with the thought of her even after his roommate leaves, because he is worried about Stradlater being a â€Å"sexy bastard† (34). After dinner, Holden goes out with his friend Mal Brossard and Ackley. When they get back, Holden starts writing the composition for Stradlater.

Twelth Night by Shakespeare Free Essays

* Characters; I have a recommended choice from either, 1. Olivia, The countess of the countess’s household. 2. We will write a custom essay sample on Twelth Night by Shakespeare or any similar topic only for you Order Now Viola, A visitor of the Island Illyria, which will later be called Cesario. 3. Malvolio, The countess’s steward. I am going to choose Viola. Because I believe that there is more information to write up on this character because of two sides’s to write about one person. (So therefore, more to write about and less research!) How would you present your character in a film/theatre production? I would present my Twelfth Night play as a film, due to sound, lighting, and computer effects, and also because you can change the scenery in a matter of second’s in a film where as you can only use 1 set in a theatre. Example; In act1 scene2 where the play mentions that the â€Å"Captain† and â€Å"Viola† are on the sea coast of Illyria with pieces of shipwreck all over the beach. After having a good old chat about where they are, it cuts short to act1 scene3 in Orsinos palace. In a theatre that would be hard to do (maybe impossible!) But in a film it would be easy. The only reason that I would go for a theatre approach is if I wanted it to be traditional. (Which I don’t!) I would also base the costumes in Elizabethan times, because then the dialect would go with the clothing. My play would be based on a Mediterranean Island that all the people that live on the island talk a hint of Italian, but not the clown (feste) and visitors. Viola is on a ship with her brother (Sebastian) and crew on their way to a unknown destination, until, a large storm hits the vessel causing all members on board to abandon ship. Most of the crew survive but are unknown in the play; the Captain and Viola escape on the same life raft and get washed up on the shores of Illyria. This island is where the whole of the play takes place and where the countess and duke both live. The play begins; The play starts off at Orsio’s palace (act1 scene1), with Orsino saying â€Å"if music be the food of love play on† (words follow) and goes to act 1 scene 2, which shows viola and the captain in a life boat all tired and disorientated, Viola â€Å"what country is this dear sir?† Captain â€Å"this place be Illyria, me lady† Viola â€Å"and what should I do in Illyria? My brother he is in Elysium. Perchance he is not drowned; what think you sir? Captain â€Å"It is perchance that you were saved, me lady† Viola â€Å"O my poor brother, he did not live to see the light of day†¦ And so perchance he maybe.† And so on so forth, they keep talking about how she has to become male to be a servant of the duke, so, the captain and her promise to not tell anyone that she’s not a man. But the bit that I find funny is that she pretends to be a male by saying that she was castrated as a young lad and that her/his voice hadn’t broke. (That was hard to explain!) Act 2 scene 1 Act 2 scene 1 tells you that Sebastian (viola’s brother) is alive and well! But not only that but he’s on the coast of Illyria as well. Act 2 scene 3 Act 2 scene 3 introduces you to feste the fool! (Clown) I find feste the most interesting character because not only is he more clever than most people on the island Example; Act1 scene5 line 53 Olivia â€Å"well, sir, for want to other idol ness, I’ll bide your proof† Feste â€Å"Good Madonna, why morn’st thou?† Olivia â€Å"good fool, for my brothers death† Feste â€Å"I think his soul is in hell, Madonna† Olivia â€Å"I know his soul is in heaven, fool† Feste â€Å"the more fool you Madonna, to mourn your brothers soul being in heaven. Take away the fool gentlemen.† but he uses technical words to humiliate other people. Feste belongs to the duke to humiliate people and to please him e.g. jokes, dance, and sing songs. Example; O mistress mine, where are you coming? O stays and hears, for your true loves coming, That can sing for both high and low. Trip no further, pretty sweeting; Journeys end in lovers meeting Every wise man son doth know. How to cite Twelth Night by Shakespeare, Papers
