Question

Diffusion is

Quizplus · Accepted Answer

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration in a liquid or gas. It is a passive process that does not require energy. Active osmosis (choice A) is not a correct definition of diffusion, as osmosis is a separate process. Choice C, molecules moving from an area of low concentration to an area of high concentration, is not a correct definition of diffusion. Passive osmosis (choice D) is not a proper term as osmosis always involves the movement of water molecules from a higher to a low concentration through a semipermeable membrane.
