Question

A lab is performed to study the effect of pH and heat on the function of the catalase enzyme found in carrot plants. What is the dependent variable(s) in this lab?

A: pH
B: temperature
C: enzyme activity
D: water

Answer 1

Hey! The correct answer is (C) enzyme activity.

Answer 2

Answer:

(C). enzyme activity

Explanation:

In an experiment, a dependent variable represents the variable, which is checked or measured during that experiment. As it is studied during the experiment, value of dependent variable gets changed by changing value of others.

In given experiment, activity of catalase enzyme of carrot plants is being tested at different pH and temperature, hence it is a dependent variable.

Thus, the correct answer is option (c).
