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)?
a) Initially, the number of water molecules moving out of the cell will exceed the
number moving into the cell; at equilibrium, the numbers of molecules moving in and
out will be equal.
b) Initially, the number of water molecules moving into the cell will exceed the
number moving out of the cell; at equilibrium, the numbers of molecules moving in
and out will be equal.
c) Initially, the number of water molecules moving into the cell will equal the number
moving out of the cell; at equilibrium, the numbers of molecules moving in and out
will be equal.
d) The cells will shrink.
E) The cells will swell.
