C) filtration
D) dialysis

Question

Quizplus · Accepted Answer

Osmosis is the movement of water molecules from an area of higher concentration to an area of lower concentration through a selectively permeable membrane. Diffusion also involves movement of molecules from an area of higher concentration to an area of lower concentration, but it does not necessarily involve a membrane. Filtration and dialysis involve the separation of particles based on size or other characteristics, but not necessarily through a membrane and not specifically for water movement.
