Question

A scientist wants to know how well bleach kills germs. The scientist applies

different amounts of bleach to samples that contain equal amounts of
germs. He then measures how many germs are killed by the bleach. What is
the responding variable in this experiment?

A. The amount of bleach used
B. The amount of time the bleach is left on
C. The number of germs killed
D. The number of samples

Answer 1

Answer is C
Remember this, Independent variable is the thing that I change. Dependent variable is the thing that depends on another variable. Lastly control variable is the thing that is kept the same.
In this case it would be C, the responding variable (aka Dependent variable). Since the amount of germs killed depends on what conditions it’s in. I hope that helps!
