Question

Kangaroo and desert rat that live in conditions of water scarcity are capable of meeting all their water requirements by

• A. Having a thick coat to minimize evaporation desiccation
• B. Oxidizing stored fat to produce water as by product
• C. Producing very concentrated urine and soloed farces
• D. All of the above
  

Answer 1

The correct option is D All of the above

Kangaroo and desert rat seldom drink water. It has a thick coat to minimize evaporative desiccation. The animal seldom comes out its comparatively humid and cool burrow during the day time. 90% of its water requirement is met from metabolic water which is produced by respiratory breakdown of fats. 10% is obtained from food. Loss of water is minimized by producing solid urine and faces.

So, the correct answer is 'All of the above'.
