Question

19. A student wants to test the effect of temperature on relative enzyme activity. The table below shows data from this experiment.What are the independent and dependent variables in this experiment?independent--temperature;dependent--relative enzyme activityindependent--relative enzyme activity;dependent--number of minutesindependent--number of minutes;dependent--relative enzyme activityindependent--relative enzyme activity;dependent--temperature

Answer 1

The variables can be independent (cause) that causes an effect on the dependent variables of the experiment, or it can be a dependent variable that is the effect caused by some action made in the study. Therefore, in the test that the student show in the table, the independent variable is the temperature, while the relative enzyme activity is a dependent variable to the temperature changes in the experiment.
