Vedclass · Answer

(B) The correct answer is $A$ only.$1$. Urea,uric acid,and ammonia are all nitrogenous waste products resulting from the metabolism of proteins and nucleic acids.$2$. They differ significantly in their toxicity: ammonia is the most toxic,followed by urea,while uric acid is the least toxic.$3$. Due to these differences in toxicity,they require varying amounts of water for excretion. Ammonia requires the most water,while uric acid requires the least.$4$. Urea is primarily synthesized in the liver via the ornithine cycle,not in the kidneys.
