For my Biology Lab I have to create a graph showing my results. We used an enzyme, and put in a substrate (H2O2). Every 10, 30, 60, 90, 120, 180, and 360 second H2O2 was killed with acid. To measure the amount of H2O2 we used KMnO4.
Now to the question. I can figure out which is the dependent variable (responds or is measured)H2O2(was measures + responded to acid and enzyme) or KMnO4 (killed H2O2 and was measured)
