Caenorhabditis elegans, abbreviated C. elegans, is a roundworm that inhabits the soil. It has played a fundamental role in Biological Laboratories since the early 1900’s as it serves as a model organism. C. elegans has the ability to distinguish between harmful pathogenic bacteria and those bacteria that prove to be nutritious through its ability to differentiate chemicals in its environment. Most of the current research on C. elegans has been conducted within laboratory constraints. We are seeking to gain a deeper understanding of the c. elegans worms within their environment. We choose to study the interactions of the C. elegans worms with bacilius subtilis, abbreviated B. subtilis, and bactillus cereus, abbreviated b. cereus for the remainder of this …show more content…
elegans live within the soil and thus are not exposed to light on a regular basis. Photoreceptors offer a unique way of “seeing” and interacting with the environment. Photoreceptors contain chemicals from which light elicits a change and thus help guide the movement and behavior of worms and other animals. Phototaxis is a type of locomotive movement that allows organisms to respond to changing light around them. Phototaxis can be both negative and positive in that a positive phototaxis is movement toward the light and that negative phototaxis is movement that is away from a light source (Department of Plant Biology). C. elegans live in the soil, thus in darkness, and do not have eyes and are therefore believed to not have photoreceptors(Wang, 2010). However, it was found that “light stimuli elicited negative phototaxis in C. elegans and that this behavior is important for survival.” (Ward, 2008). Photoreceptors are present within the c. elegans organism. As, such, “ Negative phototaxis behavior in C. elegans could function to retain worms in soil, or protect them from harmful effects of UV light” (Wang, 2010). Photoreceptors are critical to the c. elegans and their interactions within their
This year as a class we have read 2 different books. One of these books was at the beginning of the school year called “lorde of the flies.” In this book there are a bunch of kids stranded on an island due to a plane crash with no parental supervision. You see how different you are in a life where there are no rules and how savage you become when you put on a mask. These boys tested each other and themselves and at the end of the day got some people killed. The other book we read this year was Hamlet. This book was about a young prince whose father had died and his mother marries his uncle soon after. Hamlet was still grieving as his mother and uncle are having their incestual wedding. Hamlet also sometimes sees his father as a ghost and the ghost tells him that Hamlet's uncle killed the king (who is the ghost speaking to him) and this causes only cauas. Hamlet too feels alone like the boys in lord of the flies and begins doing things he never thought he would. These books opened my eyes to how different people become depending on the situation they are in and depending on how ruthless you are willing to be. I know now that if something bad happens to learn how to forgive the way Hamlet couldn’t and to let go of things.
The C. elegans were washed several times once a week for several weeks. After the final wash for each week, a small amount of C. elegans was pipetted to the middle of each plate (3 experimental plates and 1 control plate). After all the passages for the C. elegans were completed, the three avoidance assay plates were set up. (A small amount of S. marcerens was pipetted on one side of each assay plate while a small
In usual fairytale movies, filmmakers intend to make films that give happy endings with simple miraculous entertainments. However, in the fable movie, Edward Scissorhand, the director, Tim Burton, positions the viewers to understand the significant meaning of particular issues. “E.S” is can be seen as a story of stereotypical suburbia with social criticism. In this essay, starting from analysing this film and providing dominant discourse, the use of characters will be discussed followed by debate of technical and symbolic codes which help to put up the discourse. In particular, this essay will consider the technical code of camera angle and symbolic codes of colour which emphasize the dominant discourse.

Author of Lord of the Flies, William Golding, was knowledgeable of the enlightenment philosophers. He proves this through his use of the following philosophies in his novel. He demonstrates Voltaire's belief of individual rights with the conch, Rousseau's belief in which the people give the power through voting, and Locke’s belief of human nature by showing the selfishness within the boys. Voltaire believed that the government should not only protect its people's natural rights, but also their individual rights. Individual rights consist of freedom of speech, press, thought, religion, and assembly, (PIBASG Notes).
“The situation of the orphan is truly the worst, you’re a child, powerless, with no protectors or guides. It’s the most vulnerable position you can be in, to see someone overcome those odds tells us something about the human spirit. They are often depicted as the kindest or most clever of characters.” Michelle Boisseau describes how important these types of characters are. In a Sunday Times article, she states that a lot of the stories and novels are considered to be apologues about orphans becoming the hero of the book. Huck’s story is quite like this subject. The Adventures of Huckleberry Finn is a novel written by Mark Twain, it’s about a boy named Huckleberry Finn, who sets
“Persons attempting to find a motive in this narrative will be prosecuted; persons attempting to find a moral in it will be banished; persons attempting to find a plot in it will be shot.” (Twain, ix) Mark Twain opens his book with a personal notice, abstract from the storyline, to discourage the reader from looking for depth in his words. This severe yet humorous personal caution is written as such almost to dissuade his readers from having any high expectations. The language in The Adventures of Huckleberry Finn is completely “American” beyond the need for perfect grammar. “Mark Twain’s novel, of course, is widely considered to be a definitively American literary text.” (Robert Jackson,
Many themes are explored when reading Lewis Carrol’s, Alice in Wonderland. Themes of childhood innocence, child abuse, dream, and others. Reading the story, it was quite clear to see one particular theme portrayed through out the book: child to adult progression. Alice in Wonderland is full of experiences that lead Alice to becoming more of herself and that help her grow up. It’s a story of trial, confusion, understanding, and success. And more confusion. Though others might argue that the story was distinctly made for children just to get joy out of funny words, and odd circumstances, the tale has obvious dynamics that confirm the fact of it being a coming of age story.
The Hound of the Baskervilles written by Sir Arthur Conan Doyle and the movie The Hound of the Baskervilles directed by Jeremy Bret are two works of art that are mainly telling the same story. There are, however, many differences about the book and the movie. Those differences don’t affect the outcome of the story, but they give less impact to the story. Along with the differences there are many similarities, and those similarities give you confidence that it is the same story.

Jane Austen’s Northanger Abbey is essentially the “coming of age” story of Catherine Morland, a sympathetic yet naïve young girl who spends some time away from home at the impressionable age of seventeen. As Catherine matures in the town of Bath and at Northanger Abbey, she learns to forgo immature childhood fantasies in favor of the solid realities of adult life, thus separating falsehood from truth. This theme is expressed in a couple of ways, most obviously when Catherine’s infatuation with Gothic novels causes her to nearly ruin her relationship with Henry Tilney: her imagination finally goes too far, and she wrongly suspects General Tilney of murdering his late wife. The theme is less apparent

The book The Hound Of The Baskerville was written in 1901. The novel was published in serial form from 1901 to 1902. It has proved to be a great success even today and is considered by some Sherlock Holmes scholars to be Doyle’s best work. It has inspired more than twenty film and television reinterpretations, made in diverse places such as Germany, Australia, Canada, the United States, and also the United Kingdom. The most recent such reinvention of this story can be seen in the BBC series Sherlock, although this is in fact very much different from the original novel.
William Faulkner is one of America's most talked about writers and his work should be included in any literary canon for several reasons. After reading a few of his short stories, it becomes clear that Faulkner's works have uniqueness to them. One of the qualities that make William Faulkner's writings different is his close connection with the South. Gwendolyn Charbnier states, 'Besides the sociological factors that influence Faulkner's work, biographical factors are of great importance…'; (20). Faulkner's magnificent imagination led him to create a fictional Mississippi county named Yoknapatawpha, which includes every detail from square mileage of the county to the break down of
On of the most influential romantic English poets of the 19th century was Percy Bysshe Shelley. He was born August 4th 1792 to Sir Timothy and Elizabeth Pilford Shelley in Field Place, Horsham, Sussex, England. (Crook) Shelley was the oldest of six children. He had one brother, John and four sisters, Mary, Elizabeth, Hellen, and Margaret. His family lived a very comfortable lifestyle, especially his dad’s father, Bysshe Shelley whom owned quite a few estates. Shelley’s father was also a member of parliament.
