What happens when members from a separated populations do not reproduce with each other

The correct answer is-

When members from a separated populations do not reproduce with each other, they will become two different species.

According to the biological species concept of Ernst Mayor, organisms that are capable of interbreeding and producing viable and fertile offsprings belong to one species.

In this question a population has become separated and the members from the separated population do not reproduce with each other. This means that the population has become reproductively isolated and no gene flow occurs between them.

Thus, they will become two different species.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
