Question

multiple choice 0.8 points
which type of bacteria is relatively more resistant to chemicals?
gram negative
rod - shaped
pigment producer
gram positive

Explanation:

Gram - negative bacteria have an outer membrane in addition to their peptidoglycan layer. This outer membrane acts as an extra barrier, making them more resistant to many chemicals compared to other types mentioned. Rod - shaped is a morphological characteristic and not directly related to chemical resistance. Pigment - producing ability has no direct link to chemical resistance. Gram - positive bacteria lack the outer membrane of gram - negative bacteria and are generally less resistant to chemicals.

Answer:

A. Gram negative
