Answer:
Diffusion, Facilitated Diffusion
Explanation:
Diffusion is a form of passive transport of matter across the cell membrane. Diffusion is a transport substance from the middle with already in the middle with a lower concentration until the concentrations are equalized. The magnitude of the diffusion is proportional to the chemical gradient.
Facilitated diffusion, also called carrier-mediated diffusion, is the movement of molecules across the cell membrane via special transport proteins, which are incorporated into cell membranes.
