Diffusion of particles through a membrane by means of a carrier molecule is called:
pinocytosis.
osmosis.
facilitated diffusion.
dialysis.
Diffusion requires:

isotonic.
hypotonic.
hypertonic.
hydrostatic.
If a cell were placed in a hypotonic solution:
there would be a net gain of water into the cell.
there would be a net loss of water out of the cell.
no water would move into or out of the cell.
water would move into and out of the cell in equal amounts.
If a cell were placed in a hypertonic solution:
there would be a net gain of water into the cell.
there would be a net loss of water out of the cell.
no water would move into or out of the cell.
water would move into and out of the cell in equal amounts.
