B. Viruses are larger than bacteria

C. Antibiotics only work on plants

D. Viruses have cell walls that antibiotics cannot reach

8.Antimicrobial resistance is strongly promoted when:Intermediate2 pts

A. Individual immune protection and population-level transmission patterns can influence one another

B. Public health has no biological component

C. Only antibodies matter for disease control

D. Vaccination affects only the vaccinated person's genes
