The effect of light and dark environments played a role in the phenotypic frequencies of the Drosophila melangaster. In the light environment, the red eye phenotypic frequency in both males and females steadily increased, while the white eye phenotypic frequency for both males and females steadily decreased over time with each measurement. Figure 1 shows a steady increase and decrease in the phenotypic frequency of the red and white eye allelic frequencies of males, which is evident by the sideways "v" shape of the graph. The red eye allelic frequency was high in both males and females in the light environment. In the dark environment, figure 1 shows that the male allelic frequency does change for both white and red eyes. The female phenotypic
The Hobbit by J.R.R Tolkien is said to be one of the greatest children's novels of all time. The novel, due to its use of such characters as goblins, elves, trolls, giants, and others is in tradition, a fairy tale. The tale centers on a small hobbit by the name of Bilbo Baggins. It follows the journey of a band of dwarves, a wizard named Gandalf, and their robber, Bilbo on their way to retrieving treasure that had long been taken away from them. The hobbit traveled all over Middle-Earth, beginning with Bilbo's tiny hobbit-hole in the ground, to Mirkwood forest, to finally reaching the Mountain in which the dragon Smaug lives. Tolkien uses a large amount of imagery in his writing which can been seen through settings in The Hobbit. The imagery is usually either dark or light, depending on Bilbo's mood and contrast of his surroundings. J.R.R Tolkien uses dark and light imagery in The Hobbit to effectively set an eerie and mysterious mood and to foreshadow events such as Bilbo's journey in Mirkwood and his adventure in the Mountain.
When people lose their dignity, they also lose a part of the very thing that makes them human. Despair, hopelessness, fear and apathy are all ways a human can lose their humanity. The eyes provide a window onto the soul, and thus a view on the person’s mental state. The eyes also function in reverse, as a symbolic gesture of control over someone. All of this is present in Night, by Elie Wiesel, an account of human tragedy, human cruelty, human dignity, and the loss thereof.
Harry Mulisch, through his novel The Assault, conveys the Nazi Occupation in the Netherlands in 1945 giving full emphasis on the impact to people’s lives. Anton Steinwijk, the protagonist of the novel, experiences traumatic experience when the military assaulted and killed his whole family. His wish to leave what has happened to him in the past is influenced largely by his devastation and undesirable perception of the war from what he has experienced. Additionally, people around Anton also encourage him to expect a peaceful future, away from the war. Light and darkness symbolizes Anton's perception of the war and volcano ashes representing trails of his past, which influences how Anton reacts at times of trouble and when approached with information of the past.
Feeling lost when one doesn’t even know them self or when one doesn’t know what to stand for or believe in anymore is exactly how Elie Wiesel felt in his book “Night”. During the time of the Holocaust, Elie was one of the victims taken into a concentration camp and forced to work to brutal extents. As a kid, Elie was determined to learn and study his religion, but that changed, along with his priorities. Devastating events changed Elie’s idea on religion, battling conflicts between himself and those around him, even the test that God seemed to implicate on Elie. To his own disbelief, Elie had given up on God and had lost his faith due to his immense struggle throughout the year he spent in the camp, carrying the burden that he does not care about the one he had always looked up too and been there for him, which is God.

Goodness verses evil is how most novels portray light verses dark. Marilynne Robinson challenges this idea in her novel Housekeeping by changing the roles of light and dark. Light, in her novel, represents a normal life as Lucille, the protagonist’s sister, chooses to endorse. Darkness is portrayed as a source of enlightenment and a path to an abnormal life which Ruth, the protagonist, and Sylvie, the protagonist’s aunt, embrace. In the novel Housekeeping by Marilynne Robinson, the main characters, Ruth and Lucille, have to choose their lifestyle as a normal one in the light, or one that is unique in the dark.
In Joseph Conrad's Heart of Darkness, Marlow chooses a brighter path than his counterpart in Francis Ford Coppola's Apocalypse Now, Capt. Willard. The two share in the duty of searching for and discovering Kurtz, as well as taking care of his memory, but their beliefs before encountering him place the characters at opposing ends of a theme. These opposing ends are light and dark, representing good and evil.
In conclusion, melanin production has played a considerably important role in human evolution. Not only does it influence color pigmentation through its protective role of defending against harmful UV rays, but also determines detrimental features such as eye-sight and hearing. Furthermore, melanin production and its evolutionary adaptions mark an important presence upon our biological systems to this day. Therefore, in the process of furthering human evolution, melanin production has played an enormous role in human evolution by selecting for several features that allow for particular adaptions according to the human's geographical location and environment.
The objective of this experiment is to determine what genes are responsible for the white-eye color in two strains of Drosophila melanogaster, known as the common fruit fly. Drosophila is used as the experimental organism for many reasons which include its small size, easy maintenance, short 10 day generation time, and a fully sequenced genome. The characteristics of the wild type, which is the most common phenotype found in nature, include brick red eyes, long wings, gray/tan body, and smooth bristles. Of course, there are mutations that occur that cause specific traits to deviate from the wild-type phenotype. These traits include wing length, bristle shape, body color, and eye color.
The F2 punnett square shows that there should not be a female fly that has apterous wing mutation. Our observed experiment showed that female flies are capable of forming in the F2 Generation. Therefore, the mutation is located on autosomal chromosomes. In trial 1, the p value is not significant. This could be due to the fact that the male to female ratio in the F1 generation was unequal. In trial 2, the p value is significant and likely due to chance. The probability error is between 1 % and 5%.
In many cases, freewill is either present or non existent in children. During world war two, many children in Germany were deprived of their free will, and when the war was over, many German citizens were left scrambling to find freewill again. In All the Light We Cannot See by Anthony Doerr, one of the main characters, Werner, struggles with finding his voice and his freewill within a Hitler youth training school. During his experience there, he stands by and watches as one of his only friends is bullied and in the end left as a shell of his existence. Werner struggles with what he should of done and if it really is beneficial to blend in with the rest of the boys at the school; while Werner may recognize his wrongdoings and the wrongdoings of others, he feels
Light and Dark in Heart of Darkness Every story has a plot, but not every story has a deeper meaning. When viewed superficially, Joseph Conrad's Heart of Darkness is a tragic tale of the white man's journey into the African jungle. When we peel away the layers, however, a different journey is revealed - we venture into the soul of man, complete with the warts as well as the wonderful. Conrad uses this theme of light and darkness to contrast the civilized European world with the savage African world in Heart of Darkness.
An inspection of the modern animal phyla will reveal that eyes are just as diverse as they are complex. Some organisms like the rag worm have pigmented cup eyes while other like he box jellyfish have two lens eyes and two pairs of pigment pit eyes. To account for the diversity in eye structure, we must first examine the eye ‘prototype’, the original structure that was acted upon by evolution. The simplest organ that can be considered an eye is composed of a single photoreceptor cell and a single pigment cell, without any lens or other refractive body (Arendt, 2003). Such organs are know as eyespots, and...
“Sometimes, I still tell my friends I do not hate my body anymore so they would stop asking about my recovery.” (Zhang 4)
In Joseph Conrad’s novella, The Heart of Darkness, Conrad uses doubling patterns of opposition such as light and darkness, or white and black, to display and further emphasize the deceptive nature of man within the story. However, Conrad unexpectedly creates an inversion of the traditional definitions of light and dark, creating a work that establishes a theme where not everything is as it seems. Conrad uses physical locations to show the contrast between the two. Through the actual characters of the story, almost every white man, with the exception of Marlow, is portrayed negatively through such imagery. C Through his inversion of the definitions of light and dark, Conrad effectively goes to show that the white men can, at times, be more savage than the natives.
