One of the biggest ways that a species evolves is because some organisms with some traits survive and reproduce better than others. This process is known as *

This process is known as natural selection

Explanation:

Natural selection is the mechanism for which species evolve: those organisms that are more adapted to their environments are more likely to survive and to reproduce, thereby they also have more chances to transmit their genes to the next generation

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
