Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.
Atom: has equal number of +ve charge (protons) and -ve charge electrons and hence atom has charge.
Neutrons (having no charge) and protons are present in nucleus. Electrons keep revolving around the nucleus in different shells.
I believe the answer is radiometric dating.
The correct answer is bioavailability.
<span>Bioavailability is an important factor in establishing nutrient requirements and it represents the degree to which food nutrients are available for absorption and utilization in the body. The amount of a nutrient in a food that the body can actually use may vary depending on age and physiologic condition.</span>
The different sizes of animals are related to the amount of food available in these environments.
<h3>How does altitude influence species richness?</h3>
The study in mountains with increasing altitude and increased species richness at heights of evidenced, followed by a reduction in richness with increasing altitude.
With this information, we can conclude that the different size of the lizards is explained by the amount of food available in the place where it is inserted.
