2. The difference between osmosis and diffusion is: a. diffusion is the movement of water from a high concentration to low concentration b. osmosis is the movement of water from a high concentration to low concentration c. diffusion is the movement of water from low concentration to high concentration d. osmosis is the movement of water from low concentration to high concentration

The correct answer is d. osmosis is the movement of water from a low concentration to a high concentration. Diffusion, on the other hand, describes the movement of particles (including water molecules) from an area of high concentration to an area of low concentration.
