Answer the following:

Answer 1

Dear student.

8. Dialysis is a procedure that is a substitute for many of the normal duties of the kidneys like filtering of wastes in case of kidney failure.

9. Ammonotelic - Those organisms which excrete nitrogenous wastes in the form of ammonia are called as ammonotelic. Ammonia is highly soluble in water and for its elimination, a lot of water is required. Aquatic animals live in abundance of water and can afford to lose a lot of water as they would gain it very easily. So, aquatic animals are ammonotelic.

Ureotelic - Ureotelic animals are animals that excrete nitrogenous wastes in the form of urea are called ureotelic. Urea requires less water to be eliminated than ammonia and hence it has become a feature of terrestrial animals like humans.

Regards.
