L3 Cellular Transport Quiz

Reorder the following statement: Osmosis is the...

• through a semipermeable membrane

• net movement of water from a

• region of high solute concentration

• region of low solute concentration

• to a

Diffusion in the body is the​ (a)   of​ (b)   from a region of​ (c)   to a region of​ (d)   through a​ (e)   .
