Explain why living organisms
contain more hydrogen atoms than any other
atoms, yet 65% of a typical organism's mass is
oxygen.

Because Oxygen atom is heavier in mass than hydrogen atom.

Explanation:

High amount of hydrogen is present in the body in the form of water. In water, two hydrogen atoms and one oxygen atom are present. About 65 % of body mass is covered by oxygen atom, while hydrogen covers 10 % of body mass, it is because oxygen atom is 16 times heavier in mass than hydrogen atom. Mass number of hydrogen is 1 amu while mass number of oxygen atoms is 16 amu.

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
