The net diffusion of a solvent, across a semi-permeable membrane, from low to high solute concentration, is the precise definition of:
simple diffusion
facilitated diffusion
active transport
passive transport
osmosis
A solution that is described by the term hypertonic means that it is
A concentration gradient affects the direction that solutes diffuse. Describe how molecules move with respect to concentration.
