Fill in on this homework sheet i need much as possible

1. 0 because they are nonpolar,  more concentration of molecules because of a proceess called simple diffusion,

2.  o because it is a form of passive energy, low concentration,

3. molecules moving, equilibrium, higher, lower

These processes are all Passive and therefore none require energy although some are different the first is the molecules that can just pass through and yea, then thefacilitated diffusion is through moleules moving because of concentration differences, then Osmosis is when molecules because of water differences.

looks like the answer is     c     to me!
