Question

In the box provided explain why living organisms

Answer 1

Answer:

Explanation:

Living organisms are mostly made of water. Water is a molecule made from 2 hydrogen atoms and 1 oxygen atom, H2O. Now even though there are 2 hydrogen atoms for every oxygen atom in a living organism oxygen atoms are much heavier than hydrogen atoms. Hydrogen atoms are more than 15 times lighter than oxygen atoms and this is why they can be fewer atoms of oxygen in the body but they will still represent a lot of its weight.

Answer 2

Answer:

The living species comprise more number of hydrogen atoms in comparison to any other atoms, still 65 percent of the usual organism's mass is oxygen. The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom.
