Question

The kangaroo rat, which lives in conditions of water scarcity, ia capable of meeting all its water requirements by

• A. having a thick coat to minimise evaporative desiccation.
• B. oxidizing stored fat to produce water as a by-product.
• C. producing very concentrated urine and solid faeces.
• D. all of these

Answer 1

The correct option is D all of these

The kangaroo rat seldom drinks water. It has a thick coat to minimise evaporative desiccation. The animal seldom comes out of 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 nearly solid urine and faeces.
