chemical reaction between those a b c it's a reaction which occurs when heating
Ground is used for agriculture, sink water, hose water, and even drinking water (from the aqueducts).
These artificial homes preserve the resources in the animal's environment and increases population size.
<h3>What is Population size?</h3>
This is defined as the number of organisms in a population at a given place and time.
Since the resources used are artificial, they are preserved with an increase in the population due to reproduction.

Answer:
- <em><u>A. isotopes </u></em>
<em><u></u></em>
Explanation:
The <em>periodic table</em> was organized by Dimitry Mendeleiev by 1869, as he showed the connection between the atomic mass and the properties of the elements.
Nevertheless, the order of some few elements had to be altered because the properties did not follow the order of the atomic masses.
Henry Mosely by 1913 determined that atoms of a same element had different number of neutrons, leading to different atomic masses. These atoms of a same element (with the same number of protons) with different number of neutrons are known as<em> isotopes.</em>
By arranging the elements in increasing order of the number or protons (atomic number), instead of the atomic masses, all the elements resulted ordered according with a repetitive (periodic) pattern of chemical properties.
