Answers
Sand gazelles live in (1) the deserts of the Saudi Arabian peninsula. These animals allow their livers to shrink by (2) up to 30 percent—all in an effort to conserve water. It’s one of the many unusual adaptations that animals make to survive in (3) some of the hottest, driest places on (4) Earth.
How can the size of an animal’s liver affect water conservation? It has to do with (5) the cell structure of the liver and its energy needs. The cells that make up (6) the liver are packed with (7) objects called mitochondria. The mitochondria change food into (8) energy for growth and other functions in living things. This process requires oxygen, and the oxygen comes from (9) air that animals breathe. The catch? Every time you exhale, you lose water. By shrinking their livers during (10) times of extreme water shortages, sand gazelles decrease the number of active mitochondria. As a result, these animals breathe less often and, over time, lose less water.
Other mammals conserve water by (11) using it as efficiently as possible. To do this, they squeeze out every drop available to (12) them and recycle it in their bodies. The kangaroo rat, for example, is so good at (13) conserving water that it doesn’t have to drink at all. It gets all the water it needs from (14) eating seeds.
