Which macromolecule is a primary component of cell walls, and which argument provides evidence for how the structure of this molecule relates to its purpose within the cell wall? A Lipids are the primary component, and they repel and prevent excess uptake of water because they form carbon chains.

B Lipids are the primary component, and they protect the cell and help maintain its shape because they form carbon rings.

C Carbohydrates are the primary component, and they repel and prevent excess uptake of water because they form carbon chains.

D Carbohydrates are the primary component, and they protect the cell and help maintain its shape because they form carbon rings.

probably b

Explanation:

because they are close to the cell wall and they protect a cell

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
