Fill in the blanks below to complete the hypothesis for this lab. It should answer the lab question, "What is the effect of molecule size on a molecule's ability to diffuse across a semipermeable membrane?" If molecules are small enough, then they will be able to diffuse across a semipermeable membrane more easily because smaller molecules have a higher rate of diffusion compared to larger molecules.

What can a biological membrane do that a semi-permeable plastic lab membrane can't? Indicate all that apply. Group of answer choices: - Actively maintain a concentration gradient - Move molecules against a concentration gradient - Exclude molecules on the basis of size - Selectively allow different molecules of the same size to pass
