Students have asked these similar questions
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.

To determine the molarity five uniform apple cores were massed before submerging them in different molarity solutions. After 24 hours the apple cores were massed again. Then the percent change in mass was determined for the five uniform apple cores in each molarity solution.
