Question

Ammonia is chief excretory product in (1)camel and whale (2)cartilaginous fish (3)whale and tortoise (4)fresh water fish

Answer 1

When nitrogen is metabolically removed from proteins and nucleic acids then a toxic by product produced is called Ammonia.

This is released under dilute conditions by most of the aquatic animals.

Thus, ammonia is the chief excretory product in (3) whales and tortoises.

Whales are mammals, are warm-blooded and give birth to babies.

Tortoise lives on land and cannot swim in water.
