60
Transport
Passive | Active
61
Follow gradient High to low concentration Doesn't use ATP absolute 0 molecules stop moving
Passive
62
Movement of molecules from high to low till you hit an equilibrium.
Diffusion
63
Movement of water from its high concentration to lower concentration through a membrane until equalibrium
