Traits of bacteria that are different from those of eukaryotes are often good targets for antibiotic action. Many antibiotics target bacterial , which are not present in human cells.

The correct answer is: peptidoglycan cell walls and small ribosomes.

Explanation:

Antibiotics such as penicillin are great at attacking bacteria and must be used when dealing with bacterial infections.

Antibiotics work by messing with the bacteria cell wall. The bacteria cell wall is made from peptidoglycan and the strength and support given by it is key to the survival of these prokaryotes. To attack the bacteria, the antibiotics inhibit the assembly of peptidoglycan.
