um on a hot day, is there more urea formed?

no on a clod day more urea is formed i dont know how or why but i know that much that on a cold day it is more probably something to do with shivering
hope that helps

Yea lol..but actually i guess u mixed up the two features of Homeostasis...
Shivering is to do with Temperature regulation and quantity of urea is with water regulation..

can u then explain the difference between both
Thanks

if it is far then the lens becomes big to get most light rays
to do so the circular muscle relax and radial muscles contract
does this answer yr question?
kam:
your lens bulge to see the object also the integuments slacken and the ciliary muscle is pulled thin right?
thx guys soooo much
have to wait 4 2 hours tho to rep u :-[
remind me

i owe a lot of ppl reps 8)
@monnie
