Question
for a bio assignment i'm supposed to give the water balance maintenence for a fish,amphibian,a reptile,a bird,and a mammal! proublem is when i google it it gives me stuff about pools. i dont know how to find out the answer and i dont even know what she means by water balance maintenence!!!!

Answer
I do not know exactly what the teacher means either Raegan, but I  suspect she is talking about how each organism maintains its internal water balance through water loss through the lungs, skin and kidneys. You have the five classes to consider so you will have to research the water balance for each Class separately.  Start textbook material about kidney functions for each group or use google. After the kidneys look at things like sweating and water loss through breathing. I would use books first.  I will not do this homework for you but if you have a problem get back to me and I will help you
