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


Umm..no actually Less urea is Formed as on a hot day water is also lost from Sweating n so less urea is released to prevent dehydration..
hope it 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..

no..
On a hot day, when we sweat more to cool down, the body needs to conserve water so we tend to produce a small amount of concentrated urine. On a cold day a little sweat is being produced, so larger volume of dilute urine is produced.
hope this helps .. it was written in my book :)

If theres a far away  moving object, and u suddenly want to focus on it to see it clearly, what happens to ur eye to make u see the moving object clearly?

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?
