Final answer:
Salt glands help desert animals conserve water by allowing them to excrete concentrated urine and reduce water loss through urination.
Step-by-step explanation:
Salt glands enable desert animals to minimize their water loss through urination. These glands help in excreting excessive salts that they may ingest with their food, which allows the animals to conserve water by excreting concentrated urine.
Plants and animals have adapted to harsh desert environments in various ways, such as plants having features like hair on leaves and a waxy cuticle to reduce water loss via transpiration and evaporation. Similarly, desert adaptations in animals include strategies for water conservation through efficient excretion mechanisms to maintain osmotic balance.
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid.
This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location.
