1. Match each of the definitions in Column A with the appropriate term in Column B.
|Column A |Column B |
|__E__ term used to describe a solution that has a lower |a. diffusion |
|concentration of solutes compared to another solution |b. facilitated diffusion |
| |c. osmosis |
|__G__ term used to describe a solution that has a higher |d. active transport |
|concentration of solutes compared to another solution |e. hypotonic |
| |f. isotonic |
|__A__ the movement of molecules from an area of higher |g. hypertonic |
|concentration to an area of lower concentration as a result of | |
|random thermal motion | |
| | |
|__D__ the movement of molecules across a membrane that requires| |
|the expenditure of cellular energy (ATP) | |
