The three nitrogenous wastes excreted by animals are ammonia (most toxic, released by aquatic animals), urea (less toxic, excreted by mammals), and uric acid (least toxic, excreted by birds and reptiles).
Mammals give birth to live young and typically care for their offspring, while amphibians lay eggs in water and often do not provide parental care. Mammals have adaptations such as fur and mammary glands for terrestrial environments, while amphibians have moist skin and lay eggs in water for their aquatic lifestyle.
Whales are aquatic mammals, not amphibians.
No, ibex are not amphibians; they are mammals. Specifically, ibex are a type of wild goat found in mountainous regions of Europe, Asia, and North Africa. Unlike amphibians, which typically have a life cycle that includes both aquatic and terrestrial phases, ibex are fully terrestrial and adapted to their environment with features like strong hooves for climbing rocky terrains.
Most nitrogenous wastes in living organisms originate from the breakdown of proteins and nucleic acids during metabolism. These wastes are then excreted from the body through processes like urine formation in mammals and ammonia excretion in fish.
Urea is a soluble form of nitrogen waste produced in the liver from ammonia. It is the primary nitrogenous waste product in mammals and most terrestrial animals.
