A student wants to test the hypothesis that an acidic environment will decrease enzyme activity. In the
experiment, the student used an enzyme that breaks down hydrogen peroxide into water and bubbles of
oxygen. To test the hypothesis, the student should collect data on the number of oxygen bubbles produced
at different
(1) temperatures (3) enzyme concentrations
(2) pH levels (4) concentrations of hydrogen peroxide


Sagot :

The answer is (2) pH levels. The student wants to test the hypothesis which is under acidic environment. So the independent variable is pH level. And the dependent variable is enzyme activity.
