I've got a few questions..
How do cells grow and reproduce to maintain homeostasis?
What is another name for cell division?
How does removing waste help maintain homeostasis?
(this is being reposted as someone reported it for the wrong subject, and told me not to cheat of homework and stuff.. this doesn't even count for a grade, its notes..)

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
