Why Did Brown Mice Die

Submitted By
Words 248
Pages 1
As you can see, the drought caused some problems in the population. After the drought, 100% of the brown mice survived, but only 50% of the gray mice survived. The new ratio of brown mice to gray mice is 27:11. The reason all of the brown mice survived was because there was more dirt than grass now, so with their brown color they were able to camouflage. This camouflage allowed them to live long enough to reproduce and have their children replace them. The camouflage allowed the brown mice to blend in and avoid being prey. The gray mice were now exposed more, which caused them to be an easy source of prey. After collaborating with another naturalist, we found that our results were similar, both ending with brown mice having a

...“The house of eyes” What stood before me was an enormous gate, which had eroded away through time; the thin rusted iron bars were entwined and swallowed by the diseased, dried up ivy as if the roots were like witch fingers. It created a rustling noise by the chilling wind of the autumn season. I feel the mysterious place is sucking me in like a black hole filled with darkness the longer I stand out in the silent rocky pavement. The autumn leaves danced across my feet like mice while the glimmering moonlight shone upon me in front of this a distorted house. Many news have been told about “The house of eyes”, the place where people said “once you’re a part of it there’s no turning back”. I just don’t believe that ghost exist, I have to proof that. Tonight is the night. The night I shall confront “the house of eyes” It’s time now, to find out for myself if those disgusting incidents are true. My mind is hungry for the truth ever since and tonight will be the night to put my mind at rest. I walked slowly towards the rotten gates while taking a last deep breath. I squeezed through the gate; then the fingers like ivy were grabbing my leg, as if it was a warning. My legs began to tremble with fear the closer I got to the wrecked flaky door. Placed my hand on the ice-cold door handle. I swallowed anxiously, slightly turned my head delicately in the direction of the ragged gates; and took a long look of what could be my last. My fate was just a moment away, not knowing what’s next...

How Does Priestley Present Mr Birling Priestley Presents the Character of Mr Birling as a Symbol of the Capitalist Ruling Class and the Need for Socialist Ideals.

...How Does Priestley Present Mr Birling Priestley presents the character of Mr Birling as a symbol of the capitalist ruling class and the need for socialist ideals. Priestley begins by presenting Mr Birling as a successful, albeit 'hard-headed businessman'. It is clear from the stage directions which describe 'The dining room... of a fairly large suburban house, belonging to a prosperous manufacturer' that Birling is rich and materialistically successful. In terms of capitalism, he is therefore a role model in the fact that he has reached the capitalist goals of making a financial profit. Once Birling's worldy success is established, Priestley undermines his character through presenting Mr Birling as ignorant. With the play being set before WW2, dramatic irony is used when Birling exclaims 'there isn't chance of war'. Here the audience know he is wrong, and therefore realise that Birling's confidence is misguided- he is an ignorant man. This is further proven when he claims that the soon to sail Titanic is 'absolutely unsinkable'.The audience may feel there is a contradiction in this character - worldly success and power coupled with stupidity and ignorance. However, Priestley has deliberately presented Birling in this way to criticise the capitalism for which Birling stands. Being a co-founder of the Socialist Commonwealth Party, Priestley felt that his political views on socialism were very important and the play 'An Inspector Calls' is his vehicle from which to promote these...

Learning to Bend with the Road: the Childhood of Carlos Eire

...more because of the inspiring story of Carlos Eire. The memoir of Carlos Eire, Learning To Die in Miami, is a first hand account of a young Cuban refugee boy’s escape from Fidel Castro’s, Castrolandia in 1962. From start to finish Eire recounts as many memories as his conscience and subconscious will allow. In his memoir he focuses heavily on his “nine months and two weeks,” at the “Palace Ricardo.” It is evident to me that Carlos was molded and changed from the experience. In this essay I will focus on this time in Carlos Eire’s life and expose those defining moments from his, “Palace Ricardo” Phase, and argue that not only did it alter his life, it also prepared him and awakened him to his life and years to follow by learning to “bend with the road”. I will also draw from other sources to further illuminate his path to success through this difficult time. To set the tone; when Carlos Eire began his experience at “The Palace Ricardo”, he had already been air lifted from his parents and home in Cuba and shuffled from refugee holding grounds surrounded by strangers where he ate strange food in a strange land. Then he was given to a Jewish foster family. From this place of comfort he grew to love, he was quickly thrown into a house that his parents never hoped for him to end up in. This house was nicknamed by Carlos as, “The Palace Ricardo” an ironic title for a dingy, cockroach and mice infested house full of cynical and dangerous teenagers that was controlled by a selfish and...

A Black Woman’s Journey: for Colored Girls

...A BLACK WOMAN’S JOURNEY: FOR COLORED GIRLS Created in 1975, For Colored Girls Who Have Considered Suicide/ When the Rainbow is Enuf, focuses on the struggles of black women not only from that era, but issues still pertaining to black women 35 years later. Shange’s powerful choreopoem is comprised of seven women trying to "sing a black girl's song…. Sing a song of life, she's been dead so long"(Shange 18), creating a voice for every woman. None of these women possess a name, only a color, to show that they represent all women of color. Shange includes themes of love, abandonment, sexuality, abortion, and domestic violence to emphasize what women in her community were and still are subjugated to. Through dance, poetry, and music these women slowly but surely find their true identity. Ntozake uses her work as a tool to empower all “colored girls” by creating these seven strong women that form a bond when they are able to find their identity as black women, and essentially in their journey make it to the end of their rainbows without committing suicide. When looking into Shange’s life there’s no question that situations, which she had observed day-to-day or experienced herself, were imposed on her writings. Born as Paulette Williams she was raised in a middle class family, which was not a childhood common for blacks. Her family moved to St. Louis and she attended a non-segregated school where she had to endure blatant racism at the mere age of eight years old. She rebelled...

The police officers aggressively pried and tackled the girls off April. Sadly enough this was the least amount of torment she had felt in years. April was finally released that very same day, 18th of September. Stepping out into the sun, feeling the heat, sending a satisfying shiver down your spine, that should feel liberating but all she could feel was remorse and the scorching sun burning her skin. And there she was, the devil herself, Mrs. Hornburg, of all the people in West Virginia she had to be the head of Greenwood orphanage. She gave a coy smirk as she saw April coming down, her dark brown hair blowing in the wind, tall and slim silhouette, copious amounts of freckles sitting on her rosy cheeks, green, almond-shaped eyes and pink plump lips surrounded by bruises and cuts. “Now you stay out of trouble ,alright? I don’t want to see you here again.” the hefty police officer said sternly. “Of course officer, thank you and I will definitely make sure of it.” Mrs. Hornburg replied in a sweet tone but...

In that which concerns Fiction, the following documents are the ones considered as narrative: Speeches Letters Short Stories Essays Political Documents Sermons Novels Diaries 1 FIRST LITERARY EXPRESSIONS The first documents in which the idea of Americanism is very present are the Sermons. They respond to the strict Protestantism settled in the New Continent after the arrival of the Pilgrim Fathers and Puritans in the Mayflower (1620) and the Arabella (1630). They established a theocratic community whose main and only point of reference was the Bible. That is why the idea of the ‘city upon a hill’ is still very present in American mentality. As we all know, their community was also governed by the concept of Predestination. This belief was based in the idea that we are saved or condemned since the very moment we are born or even, since the very moment when the Universe was created. Therefore, the way they confronted Good and Evil was that of effect-cause: if you are one of those who were going to be saved you certainly behaved as they were...

Why Sex Is Fun

..."Why is Sex Fun? is the best book on the subject I've read. This lively exploration of our sexual heritage offers fascinating reading for anyone curious about why lovers do what they do." -Diane Ackerman, author of A Natural History of the Senses "I am so jealous of Jared Diamond, for he writes with such an elegant simplicity! Here, he takes a loot at the endlessly fascinating topic of human sexuality His convincing arguments should persuade xm that there are very special reasons why we evolved to use sex for recreation as well as for procreatim whereas most other mammals are denied that pleasure.... It is a great little book, by one of the worlds foremost biological philosophers." -ROGER Shohl Professor of Physiology Monash University Australia "Once again Jared Diamond provides us with answers to questions we may never have stopped to ask, but wish we had. In this long essay Diamond explains that recreational sex, while not unique to humans, is a rare behavior in the animal world.

...1937 OF MICE AND MEN by John Steinbeck Copyright John Steinbeck, 1937. Copyright renewed by John Steinbeck, 1965. Published by arrangement with Viking Penguin, a division of Penguin Books USA Inc. ONE A few miles south of Soledad, the Salinas River drops in close to the hillside bank and runs deep and green. The water is warm too, for it has slipped twinkling over the yellow sands in the sunlight before reaching the narrow pool. On one side of the river the golden foothill slopes curve up to the strong and rocky Gabilan Mountains, but on the valley side the water is lined with trees- willows fresh and green with every spring, carrying in their lower leaf junctures the debris of the winter's flooding; and sycamores with mottled, white, recumbent limbs and branches that arch over the pool. On the sandy bank under the trees the leaves lie deep and so crisp that a lizard makes a great skittering if he runs among them. Rabbits come out of the brush to sit on the sand in the evening, and the damp flats are covered with the night tracks of 'coons, and with the spread pads of dogs from the ranches, and with the split-wedge tracks of deer that come to drink in the dark. There is a path through the willows and among the sycamores, a path beaten hard by boys coming down from the ranches to swim in the deep pool, and beaten hard by tramps who come wearily down from the highway in the evening to jungle-up near water. In front of the low horizontal limb of a giant sycamore there is an ash...
