Another strategy (37) large desert animals is to tolerate the loss of body water to a point (38) would be fatal for non-adapted animals. The camel can lose up to 30 percent of its body weight (39) water without harm to itself, (40) human beings die after losing only 12 to 13 percent of their body weight. An equally important adaptation is the ability to (41) this water loss (42) one drink. Desert animals can drink prodigious’ volumes in a short time, and camels have been known to (43) over 100 liters in a few minutes. A very dehydrated person, (44) , cannot drink enough water to rehydrate at one (45) , because the human stomach is not sufficiently big and because a too rapid (46) of the body fluids causes death from water intoxication. The (47) of water loss is of obvious advantage in the desert, as animals do not have to remain (48) a water hole but can obtain food from grazing sparse and far-flung pastures. Desert-adapted mammals have the (49) ability to feed normally when extremely dehydrated; it is a common experience in people that appetite is lost even (50) conditions of moderate thirst.
