<span>The answer is letter B.
Almost
all chemical reactions in life processes occur in solutions with water. It
is
the most abundant molecule found in living organisms. Most mammals, in fact,
are approximately 70% water by weight. About 2/3 of this water is present inside cells. The other 1/3 is present
