Is nitrogenous waste in urine?
Urea, a nitrogenous waste material, is the end product excreted in urine when ammonia is metabolized by animals, such as mammals.
What is the advantage of excreting urea rather than ammonia as waste?

|---|---|
| The advantage of excreting wastes as urea rather than as ammonia is that: | B |
| Birds secrete uric acid as their nitrogenous waste because uric acid: A) allows birds to live in desert environments | C |
| Which of the following nitrogenous wastes requires hardly any water for its excretion? | E |
What is the advantage of excreting nitrogenous waste in the form of ammonia?
What is the advantage of excreting nitrogenous waste in the form of ammonia? Ammonia excretion conserves energy. land animals had a more difficult time with water balance than aquatic species since water was not always available on land.
What is the process of separating wastes from body fluids and eliminating them from the body called?
The basic function of the excretory system is to regulate the volume and composition of body fluids be removing wastes and returning needed substances to the body for reuse. The process of separating wastes from the body fluids and eliminating them. You just studied 20 terms!
What is the advantage of being Uricotelic?
Uricotely in Birds and Reptiles This pathway is much more energy expensive than the urea cycle of mammals with the main advantage being the excretion of relatively insoluble nitrogen-rich uric acid which is not reabsorbed from the cloaca in the adult or from the allantois in the avian embryo.
Which of the following is the most toxic waste matter?
Ammonia is the primary excretory material of many aquatic freshwater forms. It is most toxic waste material which requires large amount of water for its excretion.
How is excess nitrogen excreted from the body?
Excess nitrogen is excreted from the body. Nitrogenous wastes tend to form toxic ammonia, which raises the pH of body fluids. Terrestrial organisms have evolved other mechanisms to excrete nitrogenous wastes. The animals must detoxify ammonia by converting it into a relatively nontoxic form such as urea or uric acid.
Why do nitrogenous wastes raise the pH of body fluids?
Nitrogenous wastes tend to form toxic ammonia, which raises the pH of body fluids. The formation of ammonia itself requires energy in the form of ATP and large quantities of water to dilute it out of a biological system. Animals that live in aquatic environments tend to release ammonia into the water.
How are nitrogenous wastes eliminated from the environment?
Summary. Ammonia is the waste produced by metabolism of nitrogen-containing compounds like proteins and nucleic acids. While aquatic animals can easily excrete ammonia into their watery surroundings, terrestrial animals have evolved special mechanisms to eliminate the toxic ammonia from their systems.
Why do animals convert ammonia to urea before excretion?
Nitrogenous wastes in the body tend to form toxic ammonia, which must be excreted. Mammals such as humans excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste. Uricothelic organisms tend to excrete uric acid waste in the form of a white paste or powder.
