Answer:
Natural selection
Explanation:
Natural selection occurs when one allele (or combination of alleles of different genes) makes an organism more or less fit, that it is able to survive and reproduce in a given environment. If an allele reduces fitness, its frequency will tend to drop from one generation to the next.
Photosynthesis is a series of chemical reactions that take place in the chloroplasts, which are specialized structures found in plant cells. Through this series of reactions, carbon dioxide and water are converted to glucose and oxygen.

Grass often dies near roads that have been <span>salted to remove ice during the winter because the salt spread out into layer of the grass </span>cell. Then the water goes into the ice because the grass is attracted to the salty ice water. Hence, this dehydrates the plant cell by removing excess water, so it dies since it can no longer perform the proper cell function.<span> </span>
