1. Define diffusion.
anygoal [31]

Answer:

1) Diffusion is net movement of anything (e.g., atom, ions, molecules) from a region of higher concentration to a region of lower concentration.

2) Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides

3) One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but in osmosis, only the solvent molecules (water molecules) cross the membrane.

4)  Molecules tend to move from areas of higher concentration to areas of lower concentration.

I'm sorry, but I don't know how to do part #2. I think it's a lab.
