Answer:
17. A. from an area of high concentration to an area of low concentration.
18. A. ATP/energy is required
19. Passive transport
20. D. The solution has the same solute concentration that the cytoplasm does.
21. C. Concentration gradients
Explanation:
In passive transport substances from a region of high concentration to a region of low concentration without the input of energy. Example : Diffusion, Osmosis. temperature and pressure can affect diffusion
Osmosis is a passive transport process in which what's emotional area of less concentration to an area of higher concentration.
Cells in a hypotonic solution swell as water enters and may burst if the concentration gradient is large enough.
