Why are there no gram-positive archaea species, but there are gram-positive bacteria species?
a.
archaea lack peptidoglycan.
b.
archaea do not have a cell membrane.
c.
archaea lack chitin.
d.
archaea do not have a cell wall.

ANSWER:

The correct option is: A. "Archaea lack peptidoglycan" in the walls of the cell. Peptidoglycan is a polymer of sugar and amino acids which forms a layer around the "plasma membrane" of bacteria.

EXPLANATION:

d i think its   answer d

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
