Describes a molecule in which the positive and negative charges are separated HELP ME PLEASE !!

Polar

Explanation:

Polar is a concept which explains the formation of a particular molecule as a result of a separation of electric charges. In such molecule formed, there is a negatively charged end and a positively charged end. The difference in their electronegativity is what determines the strength of the bind formed in the molecule.

Electrically charges object can be used to attract molecules that are polar. This is because, when polar molecules are placed in an electric field, the positive charged end tends to align with the negative plate while the negatively charged end tends to align with the positive end.

Examples of polar molecules are water, hydrogen sulphide, ethanol, and some others.

the correct answer is:

a population changes in response to a change in the environment.

im not intirely sure but i think the anwser is d relative humidity
