Biology Question on Kingdom Animalia
The major excretory product of arthropods is
A
ammonia
B
urea
C
uric acid
D
trimethylamine oxide.
Answer
uric acid
Explanation
Solution
Uric acid is the end product of purine breakdown in most mammals, birds, terrestrial reptiles and insects. It is also the major form in which metabolic nitrogen is excreted except in mammals. Being fairly insoluble, uric acid can be expelled in solid form, which conserves valuable water in arid environments.
