Reabsorption of water in the hindgut of insects is controlled by which of the following?

Question

Quizplus · Accepted Answer

The reabsorption of water in the hindgut of insects is controlled by osmotic gradients created by ion pumps. These ion pumps actively transport ions across the gut epithelium, which sets up an osmotic gradient that allows water to passively reabsorb from the hindgut back into the hemolymph. This process is essential for regulating the water balance of insects, as it allows them to conserve water in dry environments while excreting waste. Selective absorptive processes that take place in the Malpighian tubules, ion concentration of hemolymph, and osmoregulators in the rectal gland are not directly involved in the reabsorption of water in the hindgut.
