Oxygen is an electronic which can be defined as pure substance..we breath in oxygen and breath out carbon dioxide
Biomolecules are important for living organisms and vital for cell structure and functioning. The cells are made up of biomolecules as their structural organization.
The four most abundant biomolecules are:
<u>Carbon, Oxygen, Nitrogen and Hydrogen</u>
The biomolecules can be explained as:
- The central biomolecules for life activities are these elements that contribute to major processes.
- The main building blocks like carbohydrate is composed of carbon, oxygen and hydrogen. They provide energy to the body by breaking into small molecules.
- Proteins are vital for cell signalling and transport. They are composed of amino groups consisting of nitrogen.
Therefore, carbon, nitrogen, hydrogen and oxygen are the most abundant biomolecules.

Answer:
A step that is not part of natural selection is people select which individuals breed and which ones do not.
Explanation:
Natural selection is a process in which favorable or unfavorable environmental conditions determine the evolution of species, producing differences in their genotype over a long period of time.
As its name indicates, it is a natural selection, in which no intervention by people is contemplated, so that <u>people cannot determine which individuals breed</u>.
Natural selection implies that the characteristics on which the environment influences are inheritable, that there is genetic variability in the population and that the variability of these characteristics implies the ease of reproduction and survival capacity.
<em>The other options do form part of natural selection, since they are based on the three premises of this process:
</em>
- <em>Inheritable characteristics.
</em>
- <em>Genetic variability.
</em>
- <em>The variability of characteristics influences reproduction and survival.</em>
