If both the assertion and reason are false |
|
Answer» Correct Answer - C (c) Ammonia is the basic nitrogenous catabolite of proteins. It is highly soluble in water and highly toxic to the animal. S its concentration must be kept very low in the blood.For this reason ammonia should be eliminated as rapidly from the body as it is needed by the animals to dissolve ammonia and eliminate it from the body. So, its elimination in urine involves considerable loss of water from the body. |
