Diffusion - ANS>>Movement of molecules from an area of higher concentration to an
area of lower concentration.
concentration gradient - ANS>>when molecules are unevenly distributed resulting in
an area of higher and lower concentration
what is the correlation between molecular mass and rate of diffusion - ANS>>the
larger and heavier the molecule the slower it will diffuse

selectivly permeable membrane - ANS>>membrane that only allows certain things to
come in while keeping other things out
