Question

How are osmosis and diffusion different? Select all that apply.

1: With osmosis, solutes cross the semipermeable membrane. With diffusion, water moves across the membrane
2: With osmosis, water crosses the semipermeable membrane. With diffusion, solutes move across the membrane.
3: Both osmosis and diffusion move from areas of high concentration to low concentration
4: Both osmosis and diffusion move from areas of low concentration to high concentration

Answer 1

Answer: 3- Both osmosis and diffusion move from areas of high concentration to low concentration

In diffusion, there is no membrane involved.

That's why 1 and 2 don't count.

Diffusion and osmosis move from an are of high concentration to low concentration, not low to high, that's why 4 doesn't count either.

hope it helps.
