B) The osmotic membrane has larger openings.
C) both a and b
D) neither a nor b

Quizplus · Accepted Answer

Dialysis membranes and osmotic semipermeable membranes both selectively allow certain molecules to pass through (such as water), but they have different mechanisms for doing so. Dialysis membranes use size exclusion to prevent larger solutes from passing through, while osmotic membranes use the process of osmosis to selectively allow solvent (usually water) to pass through, but not solutes. Therefore, neither A nor B is entirely accurate.
