You are investigating how salt affects the growth of mold
on food. Using slices of bread as the food, you create
experimental groups treated with 0 mg, 10 mg, or 50 mg of
salt. Each day you make observations and record whether
any of the groups are showing signs of mold growth.
What is the dependent variable in this experiment?
OA. The food treated with 0 mg of salt
B. The slices of bread
O C. The amount of salt used
O D. The growth of mold
