Since the relative concentration of water in the
pond in which a paramecium (a single-celled
organism) lives is greater than the concentra-
tion of water in its cytoplasm, water molecules
constantly move from the pond into the
paramecium. the best long-term solution to
the problem of maintaining a stable internal
environment is for the paramecium to
(1) change the water into carbon dioxide and
excrete it
(2) store water molecules
(3) incorporate water molecules into its
structure
(4) actively transport water molecules out of
its cell
