The arrangement of the phospholipids in the lipid bilayer is that the hydrophilic phosphate heads are oriented toward the ECF and the ICF.
9. Explain why osmosis is considered a special case of diffusion. a. Osmosis is considered a special case of diffusion because a solute moves against the gradient. b. Osmosis is considered a special case of diffusion because it is the movement of water down its own gradient. c. Osmosis is considered a special case of diffusion because it is the movement of water against its own gradient. d.
