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.

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.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
