The surface layer (s-layer) of prokaryotes choose one: a. is found only in archaea. b. is present all the time in all bacteria. c. may be lost from bacteria cultured in the lab. d. is composed primarily of saccharin.

Answer;

-May be lost from bacteria cultured in the lab

Explanation;

- The S-layer is a surface paracrystalline layer that forms the outermost cell envelope covering the entire bacterial cell, and represents a predominant surface antigen, found in almost all archaea, as well as in many types of bacteria.

-Since S-layers are found in gram-positive and gram-negative bacteria and archaea, they can be associated with quite different supramolecular cell envelope structures. In gram-positive bacteria and archaea, the S-layer subunits are linked to the peptidoglycan-containing layer or to the pseudomurein.

100 dollars because yeah

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
