Fruit Fly Degrees of Freedom

APBIO-LKNE2Z

Fruit flies (Drosophila melanogaster) are attracted to odors found in rotting fruit. A culture of fruit flies is placed in a choice chamber with the following choices: 1 mL of water, 1mL of sugar water, 1mL of salt water, and a control with no liquid added, as seen in the image below. After ten minutes, the location of the fruit flies was recorded.

How many degrees of freedom are present in this experiment?
