<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
outside cells (e.g in blood plasma or other body fluids).Without water the
proper transport and processes that occur with a cell will not efficiently
function therefore making the organism inefficient as well. <span> </span></span>
Answer:
The two potential difficulties that might have troubled Darwin’s contemporaries are:
1. Lack of transitional forms
2. Shortage of time for the varying forms to evolve.
Explanation:

This results from Darwin highlighting these difficulties in his essay.
