It doesn't.
(answer by RRU member Cyrem)
simple diffusion, osmosis and facilitated diffusion.
both need transport protein
Simple diffusion
In Biology there are three types of diffusion. There are simple, channel, and facilitated diffusion.
simple and facilitated diffusion don't require energy and are forms of passive transport. Active transport requires energy
facilitated diffusion
They both diffuse the particles in order to reduce the boner.
Passive Transport,Facilitated Diffusion, and Simple Diffusion
P.I.S.O.- Potassium in Sodium out facilitated diffusion, active transport , and passive transport and simple diffusion.
Facilitated diffusion moves molecules through cell membranes passively.
If your talking about a high concentration (outside the dialysis bag) to low concentration (inside the dialysis bag), then it's simple diffusion because it does not requires any energy, and not facilitated in any way
Passive transport. This process allows molecules to move across the cell membrane without the use of energy. It includes simple diffusion, facilitated diffusion, and osmosis.
