what the frack is the difference between urine, uric acid and urea? .. even my teachers dont know, or give some really weird fuzzy answer that has no relation to the question.. i think it's that urea is the solid...uric acid is the concentrated solution, and urine is the dilute solution.. is that right?? man i have my bio half yearly next week and dun even know this..i am sooo screwed

They are produced by different animals and have different toxicity and energy levels needed to make...

Urea- nitrogenous waste CO(NH2) and is produced by mamals and cartilaginous fishes and is the most toxic

Uric acid- also nitrogenous waste C5H4N4O3 and is produced by birds and reptiles (it has the lowest toxicity)

Urine- liquid waste produced by the kidneys after filtration of the blood and is produced by animals such as humans

urine is a slang term for nitrogenous waste
urea is how mammals excrete their nitrogenous waste... urea is soluable in water, but not toxic like ammonia is
uric acid is how birds and insects excrete their nitrogenous waste... since uric acid is not soluable, excreting it will not cause excessive water loss...
