Assertion `:-` Uricotelism is terrestrial adaptation.
Reason `:-` Uric acid is least toxic and can be removed with a minimum loss of water.

Assertion: Uric acid can be removed with a minimum loss of water. Reason: Uric acid is least toxic among the nitrogenous wastes.

Read the following statements and find out the incorrect statements. (a) Kidney plays very significant role in the removal of NH_(3) (b) Terrestial adaptation necessitated the production of more toxic nitrogenous wastes like urea and uric acid for conservation of water . (c) Some amount of urea may be retained in the kidney matrix of some of the ureotelic animals to maintain a desired osmolarity. (d) Uricotelic animals excrete nitrogenous wastes as uric acid in the form of pellet or paste with a minimum loss of water .

Animals such as reptiles, birds and insects excrete uric acid crystals with a minimum ross of water called:

Assertion :- Mostly aquatic animals are ammonotelic. Reason :- Ammonia is the most toxic form and requires large amount of water for its elimination.

Assertion :- Mostly aquatic animals are ammonotelic. Reason :- Ammonia is the most toxic form and requires large amount of water for its elimination.

Assertion: Uric acid is produced by the metabolism of purine and pyrimidine. Reason: Uric acid has high toxicity and is soluble in water.

Assertion: Uric acid is produced by the metabolism of purine and pyrimidine. Reason: Uric acid has high toxicity and is soluble in water.

Assertion: Urea is a less toxic excretory substance comparatively to urice acid. Reason: Birds and insects are ureotelic animals.
