Question: Different antibiotics target different parts/processes of a bacterial cell. Would it make sense then that a bacterium that becomes resistant to one antibiotic could still be killed by a second, different antibiotic?
Answer Choices:
Yes, if the second antibiotic targeted a different part/process than the first antibiotic.
