Which of the following may have cell walls containing teichoic acids? A) Gram-negative bacteria.
B) Gram-positive bacteria.
C) Archaea.
D) Both Gram-positive and Gram-negative bacteria.
E) All prokaryotes.

B) Gram-positive bacteria

Explanation:

The teichoic acids are usually present in most gram positive bacteria and usually extend into the thick peptidoglycan layer which is unique only to gram positive bacteria.

The teichoic acids are also important as they help to in the determination of shape and structure of the bacteria as well as regulation of cell division and replication processes.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
