Which statement best describes osmosis?
A. Osmosis is the diffusion of a solvent through a semi permeable membrane from a region of high solute concentration to a region of high solute concentration.
B. Osmosis is the diffusion of a solvent through a semi permeable membrane from a region of low solute concentration to a region of low solute concentration.
C. Osmosis is the diffusion of a solvent through a semi permeable membrane from a region of high solute concentration to a region of high solute concentration.
D. Osmosis is the diffusion of a solvent through a semi permeable membrane from a region of high solute concentration to a region of high solute concentration.
Osmosis is the diffusion of a solvent through a semi permeable membrane from a region of low solute concentration to a region of high solute concentration. The semi permeable membrane is permeable to the solvent, but not to the solute, resulting in a chemical potential difference across the membrane which drives the diffusion.

I wrote the MCAT about 8 years ago. During that time I created a whole lot of study material for myself and my friends. I want to now share it with the world. Good luck :)
