Uric acid is generally less toxic than urea. Uric acid is more soluble in water and can be excreted as a solid, while urea is more toxic in high concentrations and must be diluted in water for excretion. Additionally, high levels of uric acid can lead to conditions like gout, whereas high levels of urea can contribute to kidney dysfunction.
Ammonia is approximately 3 times more toxic than urea in terms of acute toxicity. Urea is less toxic to aquatic organisms compared to ammonia because it undergoes nitrification in water, converting it to nitrate which is less toxic.
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.
Urea is the less toxic in nature among the nitrogenous wastes where as Ammonia is 100,000 times toxic than urea.
NH4 is most toxic, in fact in mammals it is always transported in the form of glutamate, because it is so toxic. So if this is in reference to humans, that is the most likely answer. NH3 on the other hand is non toxic unless present in high concentrations for whatever reason (such as problems with excretion when it is converted to Urea
Urea is used in fertilizers and is not considered toxic. Ammonia is toxic and is what converts readily to urea.
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).
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.
Urea is a nitrogenous waste that is less toxic than ammonia. It is produced in the liver as a byproduct of protein metabolism and is excreted by the kidneys in urine. Urea requires less water to be excreted compared to ammonia, making it a more efficient waste product for terrestrial animals.
Kidneys excrete urea which is a less concentrated form of uric acid and toxic waste .
the kidney is referred to as an excretory organ and excretes urea, which is a less toxic form of uric acid.
Urea is less toxic than ammonia, making it safer to store in the body before excretion. It also requires less water to eliminate compared to ammonia, making it more energy-efficient for terrestrial animals. Additionally, the conversion of ammonia into urea consumes less energy, resulting in a net energy savings for the organism.
