Then, the fertilized egg, or zygote, undergoes to form a massive ball of identical cells. finally, the cells become specialized in structure and function through the process of

Cell division, cell differentiation

Explanation:

Cell division is the phenomena in which a parent cell divides into two or more cells. Cellular differentiation is the phenomena in which a cell changes form from one cell type to another. In general, the cell changes to a more specialized type to perform a particular function in the body.  

After the fertilization of the egg with that of the sperm the diploid cell called as zygote is formed the zygote undergoes repeated number of cell division until a considerable mass of cell develops. The cells in the mas gets specialized by the process of differentiation so as perform different functions in the embryo or developing fetus.

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

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.
