An adaptation in the structure and function of loop of Henle to the xerophytic environment is:
(a) A short loop of Henle, which allows more filtrate to be removed from the blood
(b) A short loop of Henle, which allows less water to be removed from the filtrate
(c) A long loop of Henle, which allows more filtrate to be removed from the blood
(d) A long loop of Henle, which allows more water to be removed from the filtrate
(e) A long loop of Henle, which allows less filtrate to be removed from the blood

Hint: It is a long U-shaped portion of the tubule that conducts urine within each nephron of the kidney of reptiles, birds, and mammals. This function allows the assembly of urine that's much more concentrated than blood, limiting the quantity of water needed as an intake for survival.

Complete answer:
A variation inside the structure and execution of the loop of Henle to the xerophytic climate is that they need a truly long loop of Henle, which permits more water to be removed from the filtrate. The climate in these regions is dry and hot. The main function of the loop of Henle shows to be the recovery of water and common salt from the urine.

The fluid entering the loop is the arrangement of salt, urea, and different substances passed along by the proximal convoluted tubule, from which the greater part of the broken down segments required by the body. Especially glucose, amino acids, and sodium bicarbonate have been reabsorbed into the blood. Many species that sleep in arid environments like deserts have highly efficient loops of Henle.

Additional information: The fluid entering the loop of Henle is that the arrangement of salt, urea, and different substances passed along by the proximal convoluted tubule, from which a large portion of the broke down segments required by the body—especially glucose, amino acids, and sodium bicarbonate—have been reabsorbed into the blood.
So the correct answer is ‘(d) A long loop of Henle, which allows more water to be removed from the filtrate’.

Note: During a healthy person the reabsorption of salt from the urine exactly maintains the bodily requirement: during times of low salt intake virtually none is allowed to flee in the urine, although in the duration of high salt intake the excess is excreted.
