The ozone destroying pollutants primarily comes from air conditioner coolants, refrigerator coolant, aerosol spray, and plastic foam. * true

false

true

Explanation:

Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc. The molecules of chlorofluorocarbons in the stratosphere are broken down by the ultraviolet radiations and release chlorine atoms.

C. Concentration of sugar in the water

Explanation:

The independent variable will be the variable that is changing, and the one that influences another variable.

So, in this experiment, the independent variable will be the concentration of sugar in the water.

This is because the groups of flies are given different amounts of sugar in their water, varying from 1, 2, and 3 mg/mL.

This will then impact the average length of the flies.

So, the correct answer is C. Concentration of sugar in the water
