Answer:

Explanation:

The bacteriostatic antibiotics can be defined as those antibiotics, which prevents the growth of bacteria. These keeps the growth of bacteria in the stationary phase so that bacteria cannot cause harm to the host.

The bactericidal antibiotics can be defined as those antibiotics, which kills the bacteria.

The example of bacteriostatic antibiotic is Tetracycline  that it inhibit the bacteria ribosome production of proteins. This way bacterial growth and reproduction will get restricted.

The example of bacteriocidal antibiotic is polymyxin B. It causes injuries to the plasma membrane of the bacteria which can be lethal for bacteria.
