Oxygen Deprivation In Cockroaches

For this experiment, we will be looking at the effects of oxygen deprivation in cockroaches by putting petroleum jelly on the severed cockroach leg. The energy to operate the sodium potassium pump is created by ATP, and besides food we also need oxygen in order to produce ATP, making oxygen a necessity to humans and cockroaches alike. (Gage & Marzulla) Through this experiment, we may see the effects of not being able to breathe in oxygen. Oxygen deprivation affects us very negatively, as though we may be able to store up food for days, we cannot survive more than a dozen minutes without breathing. (Gage & Marzulla) Cockroaches breathe through spiracles, which appear as holes in the side of their body, and tubes called trachea deliver oxygen …show more content…
In lab, we have not done anything very similar to this, besides the temperature lab which is still quite different. I could not find any actual data sheets from an experiment like this so mine are purely guesses. I do know for sure that as the temperature lab, but the spikes will eventually stop, and start back up again, unless this experiment was repeated over on the same leg, thus drying out the leg. As Davis & Slater state, when the common cockroach is deprived of oxygen, it enters a state similar to anathesia, and this can be reversed by replacing the air. If the deprivation is not too long, readmission of the air will quickly revive the cockroach. (Davis & Slater, 1926) As found by Gage and Marzulla, there is an alternative way to conduct this experiment, though I did not find it realistic for our class. This method required a positive airflow container, an oxygen tank, an argon tank, some regulator, and tubing. In this, the cockroach leg is placed inside the container, and the tanks will slowly decrease the percentage of oxygen, reflecting the effect of spiking activity as the oxygen is being removed from the container.

It is autumn, a beautiful October morning. The country air is cool but fresh. The young girl hears happy music approaching her house. She is only eighteen, and she is nervous, frightened. She knows that many marriage introducers simply take money and tell lies. Some women from her village marry men who don't have all their functional body parts. Those women have to spend the rest of their lives looking after their husbands. Wife beating is common. Divorce is out of the question. Divorced women are humiliated, despised, suffering worse than an animals fate. She knows some women hang themselves instead and she prays this is not going to be her fate. She prays to a kind and merciful god that her future husband will have two legs, two arms, two eyes and two ears. She prays that his body parts are normal and functional. She worries that he will not be kind-hearted and will not like her. But most of all she &+x worries about her unbound feet. Bound feet are still in fashion.

...C h a p t e r 1 Prewriting GETTING STARTED (OR SOUP-CAN LABELS CAN BE FASCINATING) For many writers, getting started is the hardest part. You may have noticed that when it is time to begin a writing assignment, you suddenly develop an enormous desire to straighten your books, water your plants, or sharpen your pencils for the fifth time. If this situation sounds familiar, you may find it reassuring to know that many professionals undergo these same strange compulsions before they begin writing. Jean Kerr, author of Please Don’t Eat the Daisies, admits that she often finds herself in the kitchen reading soup-can labels—or anything—in order to prolong the moments before taking pen in hand. John C. Calhoun, vice president under Andrew Jackson, insisted he had to plow his fields before he could write, and Joseph Conrad, author of Lord Jim and other novels, is said to have cried on occasion from the sheer dread of sitting down to compose his stories. To spare you as much hand-wringing as possible, this chapter presents some practical suggestions on how to begin writing your short essay. Although all writers must find the methods that work best for them, you may find some of the following ideas helpful. But no matter how you actually begin putting words on paper, it is absolutely essential to maintain two basic ideas concerning your writing task. Before you write a single sentence, you should always remind yourself that 1. You have some valuable ideas to tell your reader,...
