The development of organs and tissues from a zygote includes

mitosis and differentiation

Explanation:

During the early stages of development, the cells that are formed by MITOTIC division (mitosis) begin to undergo DIFFERENTIATION, which simply means that they become different from one another. This leads to the formation of specialized cells, which form the tissues, and then the organs, of multicellular organisms.

answer: mannn ion even know fam

explanation: just try asking yoo teacher yo parents or just simply another sight

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
