In nature, organisms mate without human interference. this is called a) artificial selection. b) selective breeding. c) non-random mating. d) random mating.

D)random mating.

Explanation:

When organisms mate without human interference naturally it is known as random mating. In such mating, each individual of a particular species mates with any of the opposite sex counter part. The individuals of a particular sex are free to choose their mate and in this case each individual of the opposite sex is equal potential partner of opposite sex individual. Such population is known as panmictic population and any sort of recombination is possible in such population because there is no restriction in the selection of mates.

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
