Question

Quizplus · Accepted Answer

The desert environment is characterized by high temperatures and limited water availability, which requires organisms to be highly efficient in water conservation. The nephrons with loops that extend deep into the renal medulla are responsible for the production of concentrated urine, which is important for water conservation. Therefore, natural selection should favor the highest proportion of nephrons with loops of Henle that extend deep into the renal medulla in the mouse species living in a desert environment.
