Abstract This experiment focuses on the effects water bath temperatures have on D. melanogaster entering and recovering an anoxic coma. It was found that there was an indirect relationship between the amount of time it took D. melanogaster to enter and recover from an anoxic coma and the temperature of the water bath. D. melanogaster was able to enter and recover from the anoxia coma quicker when they were drowned in a cold water bath condition when comparing these results to the warm water bath

Discussion: Referring to the hypothesis we predicted in the beginning of this experiment that under ideal conditions‚ we hypothesized that the results will eventually follow the Hardy-Weinberg expectations‚ which means the genotypes frequencies of the Drosophila melanogaster would remain constant; Therefore‚ no evolution had happened to the flies under the ideal conditions. After the chi-squared values were found in each week (table 1)‚ in the third generation where the chi-squared was found to

7 July 2013 Brain regions where ideas become contagious identified by Will Parker How do ideas spread? Why do some videos go viral? UCLA scientists have taken a first step toward answering these questions by identifying the brain regions associated with the successful spread of ideas. The research‚ reported in the journal Psychological Science‚ has broad implications and could lead to more persuasive advertisements and better ways for teachers to communicate with students. The study suggests

One day I noticed that the bananas in my kitchen were always turning brown quickly. I wondered which fruit decomposes the fastest. Id ecided to compare a banana‚ pear‚ apple‚ strawberry‚ and orange. I gathered my materials: 1 of each fruit‚ 5 see-through disposable plastic containers‚ and my camera (so I could take pictures of the fruits). My hypothesis was that the strawberry would rot first‚ followed by the banana‚ then the pear‚ and then the apple. I didn’t think the orange would even rot at all

A Study Of Inheritable Traits in Fruit Flies INTRODUCTION The Drosophila melanogaster‚ more commonly known as the fruit fly‚ is a popular species used in genetic experiments. In fact‚ Thomas Hunt Morgan began using Drosophila in the early 1900’s to study genes and their relation to certain chromosomes(Biology 263). Scientists have located over 500 genes on the four chromosomes in the fly. There are many advantages in using Drosophila for these types of studies. Drosophila melanogaster can

Healthcare for workers has been difficult to quite understand. It comes with many issues and solutions in which many are not talked about or understood. In Fresh Fruit Broken Bodies‚ Seth Holmes talks about the fieldworks and the injuries that happen to these workers. The main focus with cultural competency is the lack of training that one has in the health field training. He explores the structural factors that affect the migrant healthcare and how the health professions perceive these migrant patients

Block 1 January 24‚ 2011 Introduction & Background Fruit flies have made a huge contribution towards knowledge about genetics‚ but for most people‚ they are just annoying insects that are attracted to their fruit. Their scientific name is Drosophila melanogaster‚ and to scientists‚ they have been a key to understand many principles of heredity including sex linked inheritance‚ epistasis‚ multiple alleles‚ and gene mapping. Fruit flies were the first organisms to be used for genetic analysis

INTRODUCTION Worldwide postharvest fruit and vegetables losses are as high as 30 to 40% and even much higher in some developing countries. Reducing postharvest losses is very important; ensuring that sufficient food‚ both in quantity and in quality is available to every inhabitant in our planet. Proper postharvest processing and handling is an important part of modern agricultural production. Postharvest processes include the integrated functions of harvesting‚ cleaning‚ grading‚ cooling‚ storing
