The main objective of this lab is to determine if fruit flies are attracted to rotten apples. The experiment focuses on the chemotaxis of fruit flies in response to small amounts rotten apple juice. We hypothesised that if the fruit flies were exposed to rotten apples, then they would have a positive chemotaxis because they are attracted to the mold and bacteria on the rotten apple and also recognize that it's a source of glucose. The first part of the investigation involved evenly distributing the fruit flies into the choice chamber and exposing them to the rotten apple juice and water. To see if they had positive chemotaxis we placed about 10 drops of the juice on the cotton ball and 10 drops distilled water on another cotton ball. While
