Many antibiotics work by preventing bacteria from building a strong cell wall that can protect them. For example, the antibiotic penicillin keeps bacteria from making the most common molecule that is needed to build their complete cell walls. This causes the cell wall to burst and the bacteria to die. Would antibiotics also work to destroy viruses? A. Yes, because all viruses have cell walls.
B. Maybe, because only some viruses have cell walls.
C. No, because viruses have a cell membrane but no cell wall.
D. no because viruses do not have cells at all
