"<span>Let's start with the basics: you have
probably heard that your body is 90% (or 85% or 95%) water. In actual
fact, water is (probably--unless you are obese) the majority of your
body weight--but nowhere near 90%. The best estimate I have seen is 57%
(Body water). So that puts hydrogen and oxygen in the top four.
As
I mentioned, extremely obese people can be less than 50% water. Fat
(triglycerides) is composed of carbon, hydrogen, and oxygen. The
majority of the mass of a triglyceride is carbon--chemically it is
closely related to biodiesel. So that puts carbon in the top four.
Finally,
amino acids which make up proteins (which make up muscle) require
nitrogen. That makes the top four.: Oxygen, Carbon, Hydrogen, and
Nitrogen.
But wait! What about bones? Aren't they calcium and phosphorous? Bones are really heavy.
It
turns out that calcium and phosphorous are indeed the next two most
abundant (by mass) elements in the body, but where nitrogen is about 3%
of your body mass, calcium and phosphorous are 1.5% and 1.2%
respectively.

Answer:
good question
Explanation:
probably because people like to say they know things and help people with "there stress" and think that there helping them but in reality there making it where they have more :)
G. H2S contains two hydrogen atoms
While terrestrial biomes are shaped by air temperature and precipitation, aquatic systems are characterized by factors such as water salinity, depth, and whether the water is moving or standing. If that's what you mean?
