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

investigate the vitamin C content of fruit juice * To investigate which type of fruit juice provides the most vitamin C The quantity of vitamin C in food and drink can be determined using a simple colour test. Vitamin C decolourises the blue dye DCPIP (dichlorophenolindolphenol). Vitamin C is an antioxidant and reduces the DCPIP. DCPIP changes from blue to colourless (or slightly pink) as it becomes reduced. We will be testing a range of different fruit juices to see which contains the highest

In future study of Drosophila melanogaster‚ I suggest that the study is carried over longer time‚ and larger number of flies‚ to give a more precise and accurate results. Another thing I suggest is providing special equipment for this experiment such as special brushes to move the flies not
