What is diffusion? a. The movement of molecules through a semi-permeable membrane from an area of lower concentration to an area of higher concentration. b. The movement of molecules through a semi-permeable membrane until there are equal amounts of on each side of the membrane. c. The movement of molecules through a semi-permeable membrane from an area of higher concentration to an area of lower concentration. d. Molecules desire to spread as far from a membrane as possible.
