Which is an environmental factor that affects skin color in humans? amount of food consumed amount of sunlight absorbed number of genes inherited number of linked genes

Amount of sunlight absorbed

Explanation:

The amount of sunlight absorbed by the body affect the color of the individual. Rest all the factors that affects the color of the individual are genetic factors.

The person who absorbs more sunlight will have more melanin concentration or amount in their cells as as compared to the person who absorbs less sunlight.

Hence, the correct answer is option sunlight absorbed.

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

answer; i believe the answer is (polygenic inheritance;
