Question

in birds excretion of nitrogeneous wastes mainly as
uric acid is helpful for
1 eliminating excess body water
2 conserving body water
3 eliminating excess body heat
4 eliminating excess sugar​

Answer 1

Explanation:

2) conserving body water

Explanation- Uric acid is excreted by the animals which conserve water, at least during parts of their life cycle, such as birds, terrestrial reptiles, insects and some snails. In this case ammonia is converted into uric acid because it is less toxic than ammonia but it is insoluble in water. Uric acid is excreted in crystalline form mixed with, but not dissolved in, small amounts of water. In fowls (chickens and turkeys), blood level of uric acid is about 5 mg/100 ml, while insects have as much as 20 mg uric acid/100 ml of blood
