Question

Which of the answer choices correctly lists the three forms of nitrogenous waste in order from least to most toxic? uric acid, ammonia, urea urea, ammonia, uric acid ammonia, urea, uric acid urea, uric acid, ammonia uric acid, urea, ammonia

Answer 1

uric acid < urea < ammonia

Step-by-step explanation:

• Such types of metabolic wastes that contain nitrogen are called nitrogenous wastes such as ammonia, urea, and some other.
• The formation of these waste materials are based on the nature of the organisms such as urea and uric acid are the common nitrogenous waste of the terrestrial organisms.
• Ammonia is generally produced in freshwater fishes and some other marine organisms.
• Since ammonia requires a sufficient amount of the water to excrete out so aquatic organisms excrete this wastes.
• Ammonia is more soluble in water has the highest toxic nature than other nitrogenous wastes.
• The organisms that produce ammonia as waste products are called ammonotelic organisms such as fishes, protozoans, and some other aquatic organisms.
• The organisms that produce urea as waste material are known as ureotelic such as mammals and some other.
• Urea has a less toxic effect than the ammonia molecule.
• Uricotelics are those organisms that excrete uric acid as nitrogenous waste such as birds, reptiles and some other.
• Uric acid is the least toxic in comparison to urea and ammonia.
