What are the three nitrogenous waste excreted by animals?
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).
What is the form of nitrogenous waste that most fish give off?
Most fish excrete nitrogenous waste in the form of ammonia. Ammonia is highly toxic, but fish eliminate it primarily through the gills and some through the urine. Some fish species, particularly those living in environments with low water availability, convert ammonia to a less toxic form, such as urea or uric acid, before excreting it.
What is the nitrogenous waste in urea?
The nitrogenous waste in urea primarily comes from the breakdown of proteins and nucleic acids in the body. During metabolism, amino acids undergo deamination, where the amino group is removed and converted into ammonia, which is toxic at high levels. The liver then converts this ammonia into urea, a less toxic compound that is excreted by the kidneys in urine. This process helps to safely eliminate excess nitrogen from the body.
What is the main nitrogenous waste expelled in urine and say where it is made?
The main nitrogenous waste expelled in urine is urea, which is produced in the liver through the urea cycle. This process converts ammonia, a toxic byproduct of protein metabolism, into urea, which is less harmful and can be easily excreted by the kidneys. Urea is then filtered from the blood and eliminated from the body in urine.
List Three main nitrogenous wastes of animals what is the relative need for water?
The three main nitrogenous wastes in animals are ammonia, urea, and uric acid. Ammonia is the most toxic and soluble in water, requiring a high volume of water for its excretion. Urea is less toxic and requires a moderate amount of water for excretion. Uric acid is the least toxic and least soluble, needing very little water for excretion.

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).
The least toxic of nitrogenous wastes is?
Urea is the less toxic in nature among the nitrogenous wastes where as Ammonia is 100,000 times toxic than urea.
What is the advantage of excreting nitrogenous waste in the form of ammonia?
Ammonia is less soluble than uric acid.

Terrestial animals are generally either ureotelic or uricotelic not ammonotelic why?
Ammonia is a highly toxic compound. So it shouldn't be stored in an organism's body for a long time. The problem is that ammonia can only be eliminated in a solution (because it is higly soluble). Aquatic animals are sorrounded by water, so water conservation is not a problem for them. In this manner, they are continously eliminating ammonia, in some cases even through their skins. On the other hand, terrestrial animals have to conserve water. They cannot waste it, so ammonia (in a solution) can't be eliminated continously . Since ammonia is highly toxic, it has to be converted to a less toxic form, like urea or uric acid. Both of them can be eliminated when the organism has enough water to spend.
Is uric acid more toxic than ammonia?
Uric acid is less toxic than ammonia. Ammonia is highly toxic to the body and can cause damage to cells and organs. Uric acid, on the other hand, is a waste product formed from the breakdown of purines and is usually excreted by the kidneys in the urine.
What is a nitrogenous waste for chicken?
The primary nitrogenous waste for chicken is uric acid. Chickens excrete uric acid as a white, semi-solid paste along with their feces, which helps conserve water and maintain a good balance of electrolytes in their bodies. Uric acid is the result of the breakdown of proteins in the liver and is less toxic than other nitrogenous waste products like ammonia or urea.
How many times urea is less toxic than ammonia?
Urea is approximately 1.5 times less toxic than ammonia. This is because urea is less alkaline compared to ammonia, which can cause burns and irritation. However, both substances can be toxic if ingested in large amounts.
How is your nitrogen waste different from a bird's nitrogen waste?
Ammonia has only one nitrogen per molecule, but it is quite toxic. It requires a great deal of water to be flushed out of the body. Reptiles including birds go one step further, packaging their nitrogenous waste as uric acid. That white stuff you see from a bird or a snake it has less water in the poop.
Why ammonia is more toxic than urea?
Ammonia is more toxic than urea because it is a strong alkaline compound that can disrupt cellular processes and cause damage to tissues and organs. Urea, on the other hand, is a less toxic waste product that is more easily excreted by the body in urine.
Why would it be disadvantageous for humans to excrete nitrogenous waste in the form of ammonia?
Would be disadvantageous because ammonia destroys the ozone layer. If we were to excete mass ammounts of a harmfull substance we would therefore be destroying life on earth by destroying our protective ozone layer. Hope this helps :)
