Question

2. which of the following correctly identifies active transport?

3. how is osmosis different from diffusion?

Answer 1

both describe the movement of particles across semi-permeable layers (in this context). Osmosis is only for water molecules (solvent), diffusion is for solute particles.

Answer 2

osmosis and diffusion differs in the way that in osmosis semi-permeable membrane is involved while not in diffusion.

Answer 3

diffusion DOES involve semi-permeable membranes when contrasted with osmosis. Although diffusion can also mean the dispersion of particles in a medium.
