Text Solution

Verified by Experts

The correct Answer is:
C

Camels have the ability to withstand water deprivation for long periods. But they do not store any water in the pouches of their rumen. The fat of hump is not particularly useful as a source of water because respiration must be enhanced respiratory loss of moisture. They reduce urinary water loss b secreting small volume of the urine much more hypertonic than the human urine. They lose far less water in the sweat, because they sweat only when their body temperature rises by as much a s`60^(@)C` , compared to all other mammals. These factors are mainly responsible for the camel's ability to go without water for long periods.
