5 to 10 percent
10 to 20 percent
35 to 50 percent
50 to 75 percent

 10 to 20%

Explanation: The normal input of water inside the body is about 2.5 liters from beverages and the food that we eat.

The normal output of water is 2.5 liters that consists of 1.8 liters of urine, feces, sweat and 0.7 liters of insensible water loss.

The amount of water loss varies with the air, temperature, humidity and the environment n which a person is living.

This correspond to 10 to 20% of water loss through respiratory system.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
