Final answer:
The experiment tests the hypothesis by examining the factors that are varied and constant in the lab procedure.
Step-by-step explanation:
The experiment tests the hypothesis by examining the factors that are varied (V) and constant (C) in the lab procedure. The factors that are varied include the molecule size (V), whether the molecules diffused through the membrane (V). The factors that are constant include the material used as the membrane (C), the amount of substances used (C), and the number of trials (C).
