Question

if i feed bacteria powdered cheetos, then bacterial growth will decrease. amount of cheeto powder independent variable dependent variable control constant

Explanation:

In an experiment, the independent variable is the factor that is deliberately changed or manipulated. Here, the amount of Cheeto - powder being fed to bacteria is what the experimenter is changing. The dependent variable would be the bacterial growth (which is expected to change based on the independent variable). A control is a standard for comparison (not the amount of Cheeto - powder). A constant is something that stays the same throughout the experiment (not the amount of Cheeto - powder).

Answer:

A. Independent variable
