natural selection is the trait that better helps something adapt to its environment.

a disadvantage is that if one plant disease can wipe out an entire population of cloned plants and an other onincreased competition

advantage is assists with survival and It increases the chance that at least some offspring of a parent survive.

cytosine C4H5N3O: Cytosine is one of the four main bases found in DNA and RNA, along with adenine, guanine, and thymine. It is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached. The nucleoside of cytosine is cytidine

thymine C5H6N2O2: Thymine is one of the four nucleobases in the nucleic acid of DNA that are represented by the letters The others are adenine, guanine, and cytosine. Thymine is also known as 5-methyluracil, a pyrimidine nucleobase.
