A solution of water and dissolved ions is separated by a selectively permeable membrane that allows the passage of water but not small ions. The concentration of sodium is higher on one side of the membrane than onthe other side. However, there is no net movement of water across the membrane. How is this possible?
Tight junctions prevent the diffusion of fluids and solutes between______________
Solution A is hyperosmotic to solution B. If solution A is separatedfrom solution B by a selectively permeable membrane, does watermove from solution A into solution B, or vice versa? Explain
