Uric acid is the least toxic metabolic product of protein metabolism, which gets excreted by the urine.
Uric acid is the least harmful among ammonia and urea.
Choose the least toxic form among them - India Site. explanation – uric acid is less toxic than urea , ammonia and carbon dioxide . It has four nitrogen atoms so very less amount of water is required to excrete it out .
Compared to ammonia and urea, uric acid is least toxic and least soluble in water.
Ammonia, urea and uric acid are the major forms of nitrogenous wastes excreted by the animals. Ammonia is the most toxic form and requires large amount of water for its elimination, whereas uric acid, being the least toxic, can be removed with a minimum loss of water.
Ammonia is the most toxic nitrogenous waste and requires a lot of water to be flushed out of the body.
Ammonia is the primary excretory product. Ammonia is derived from the food containing proteins. It is considered as the most toxic nitrogenous waste.
So, the correct answer is 'Urea'.
Excretion Meaning
In animals, the main excretory products are: Ammonia. Carbon Dioxide. Urea.
The kidneys remove waste products called urea from the blood through tiny filtering units called nephrons.
Ammonia: The most toxic nitrogenous waste is ammonia. Its excretion requires a huge quantity of water. The least toxic nitrogen-containing waste is uric acid.
The nitrogenous wastes in the human body is removed by the kidney through ultra filteration. The purified blood is carried away from the kidney through renal vein towards the heart. Hence blood in the renal vein will have minimum nitrogenous wastes. So, the correct answer is 'Renal vein'.
Urea is less dangerous than ammonia in terms of toxicity.
So, the blood in renal vein has less nitrogenous waste than the blood in renal artery.
A non-toxic substance is one that is not expected to cause symptoms or be dangerous. A good example is silica gel. Most of us have seen this packet in new shoe boxes, cameras, purses, coffee cans, and medicines.
Non-toxic elements such as iron (Fe), calcium (Ca), magnesium (Mg), selenium (Se), zinc (Zn), potassium (K), copper (Cu) and sodium (Na) are required for oxygen transport, energy production, blood pressure regulation, proper bone formation and serve as coenzymes in humans [7.
Radon in basements, lead in drinking water, exhausts from cars and chemicals released from landfills are just a few examples of toxic substances that can hurt you. By understanding how, you can reduce your exposure to chemicals and reduce your risk of harmful health effects.
See also: Carbonic Acid (related); Dry Ice (related). Carbon dioxide appears as a colorless odorless gas at atmospheric temperatures and pressures. Relatively nontoxic and noncombustible. Heavier than air and may asphyxiate by the displacement of air.
Compared to ammonia and urea, uric acid is least toxic and least soluble in water. Q. The following substances are the excretory products in animals.
Uric acid is the least toxic nitrogenous by-product.
Incinerators. Incinerators are used to burn hazardous waste primarily for waste destruction/treatment purposes; however, some energy or material recovery can occur. When performed properly, incineration destroys the toxic organic constituents in hazardous waste and reduces the volume of the waste.
Hazardous, or toxic, waste is the potentially dangerous byproduct of a wide range of activities, including manufacturing, farming, water treatment systems, construction, automotive garages, laboratories, hospitals, and other industries.
