Question

Lactobacillus acidophilus (below) is a probiotic microorganism typically found in the human small intestine. It has a cell wall made of peptidoglycan. It aids in the process of digestion and can commonly be obtained through sources such as acidophilus yogurt. Which characteristic proves Lactobacillus acidophilus is from the specific kingdom Eubacteria?

It is multicellular.
It has a cell wall.
It is a microorganism.
It has peptidoglycan.

Answer 1

its D. It has peptidoglycan.

Step-by-step explanation:

Answer 2

The right answer is It has peptidoglycan.

Eubacteria are not multicellular beings, but are unicellular.

Eubacteria certainly have a cell wall, but we must not forget that plant cells also have a cell wall, so this is not really a feature.

Eubacteria are microorganisms but there are eukaryotic microorganisms, so it is not a characteristic.

Peptidoglycan (or murine, or mucocomplex, or mucopeptide) is a characteristic component of the bacterial wall (not found elsewhere) maintaining the shape of cells and providing mechanical protection against osmotic pressure. It forms a thin layer in Gram-negative bacteria and a thick layer in Gram-positive bacteria.
