Answers:
1. Facilitated diffusion: the process by which some molecules that are not able to pass directly through a cell membrane are able to enter the cell with the aid of transport proteins.
2. Osmosis: the diffusion of water molecules through a selectively permeable membrane.
3. Diffusion: the spreading out of molecules across a cell membrane until to they are equally concentrated.
Step-by-step explanation:
Diffusion is the spontaneous movement of molecules across a membrane from an area of high concentration to one of low concentration gradient.
Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of low solute concentration to one of high solute concentration.
Facilitated transport occurs when molecules cannot diffuse directly through a cell membrane but can diffuse down a concentration gradient through transport channels in the membrane.
