The outer membrane contributes an extra barrier in gram-positive bacteria that makes them impervious to some antimicrobial chemicals, so they are generally more difficult to inhibit or kill than are gram-negative bacteria. A. TrueB. False

The statement is false

Explanation:

Gram-positive bacterial cell wall is made up of only the peptidoglycan layer and it does not have an extra barrier that protects it from some antimicrobial chemicals. Gram-negative bacteria have two layers of cell wall peptidoglycan layer and a lipopolysaccharide layer.

So as gram-negative bacteria have an extra layer of cell wall therefore it is less sensitive towards antimicrobial chemicals than gram-positive bacteria. So grams positive bacteria are an easy target for antimicrobials than gram-negative bacteria. Therefore the statement is false.

the answer would be knowledge about cars!
