When organisms reproduce, they pass on
A.
behaviors that they learned during their lifetimes, such as how to play the piano.
B.
characteristics that they acquired during their lifetimes, such as scars.
C.
the hereditary traits that are found in the genes in their cells.
D.
all of these

its C I think. I'll tell you why if I'm wrong tell me

Explanation:

so the.cells hold Gene's that come from the parent or organism

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
