The eyes are the same size from birth.
If you are referring to the size of various body parts, the answer is the EYES. They remain the same size from birth to death.Hope this helps.
None, your body stays the same
Your mass is the amount of stuff that makes up your body. Since you do not leave part of yourself behind or add anything to your body, your mass stays the same.
Vertebrate animals are able to stay at the same body temperature no matter where they live
It feels the same as you would give birth. But it does seem to apear that when the foals shoulders need to come out (the widest part of the body) it causes the most sound.
No boss its not like what you are saying, Eye's will remain same in size till to death from birth, this is what natures beauty.instead of this all organs will change there size. I don't think there is any body part or organ in humans that remains the same from birth to adulthood. There must be some form of changes if that body part or organ is normal.
it normally stays the same
the body part is the liver it is the same size of the heart
Heating gasses or liquids has no effect on their masses.
