Uric acid produced by insect Malphigian tubules does not influence the movement of water from the hindgut because:

A. it is eliminated by the tubules before water
reaches the hindgut.
B. it precipitates due to the low pH of the fluid
in the rectum and therefore does not
contribute to osmotic pressure.
C. water moves only in response to the
osmotic pressure created by proteins and
sugars in the hindgut.
D. uric acid is equally concentrated in the
hindgut and in the body fluids.
E. None of these choices are correct.
