Question
The NaCl concentration in physiological saline solutions is 0.9%. If animal cells are transferred from physiological saline to a solution of 10% NaCl, which of the following will happen (choose all that apply)?
Question 1 options:
A) Initially, the rate of movement of water molecules out of the cell will exceed the rate of movement into the cell; at equilibrium, the rates will be equal.
B) Initially, the rate of movement of water molecules into the cell will exceed the rate of movement out of the cell; at equilibrium, the rates will be equal.
C) Initially, the rate of movement of water molecules into the cell will equal the rate of movement out of the cell and these rates will not change at equilibrium.
D) The cells will shrink.
E) The cells will swell.
