Map dd Sapling Learning Classify each statement as applying to osmosis, dialysis, or both osmosis and dialysis. Osmosis Dialysis Both may be used as a way to separate small molecules involves the movement of small particles across a involves the movementcan be used medically of water across a in artificial kidney semipermeable membrane machines to remove urea and ions from coliloids semipermeable membrane involves the movement of water across a cell membrane Solution Dialysis is the separation of suspended colloidal particles from dissolved ions or molecules of small dimensions by means of their unequal rates of diffusion through the pores of semipermeable membrane. Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. So osmosis involves involves the moment of water across the semipermeable membrane. Involve the momentum of water across cell membrane. Dialysis Can be used medical in artificial kidney machines to remove urea May be used as a way two separate small molecules and ions from colloids. Both Inverse the momentum of small particles across a semipermeable membrane. .
