Answer:
Cheek cells are eukaryotic cells
HbA HbS
is the correct answer, just tested it
Animals, they only have a cell membrane, not cell walls.
I don't know what the answer choices were, though, but I hope this helps.
Osmosis only talks about water molecules
Diffusion talks everything other then the water molecules.
So,
Osmosis : water molecules travel from a region of a higher water potential to a region of lower water potential through a partially permeable membrane via osmosis
Diffusion : Travels from a region of higher concentration to a region of lower concentration through a partially permeable membrane via diffusion
