Question

Reptiles and birds excrete waste as an insoluble white solid that is called uric acid how does this help them to maintain internal homeostasis in hot climates

Answer 1

By excreting solid uric acid, reptiles and birds are able to conserve water that can be used for other metabolic processes.

Answer 2

The correct answer is by retaining water.

Step-by-step explanation:

Eliminating uric acid as a waste assists the birds and reptiles in sustaining the internal homeostasis in hot weather by reducing water loss or by retaining water. The reptiles and birds transform the toxic ammonia to uric acid, while on the other hand, the mammals transform ammonia to urea.

Generating uric acid in place of urea is less toxic, and at the same time, excreting uric acid minimizes loss of water that plays a significant role in hot climatic conditions.
