This question is about pathogens and treatments.
A scientist investigated the effectiveness of different antibiotics on a strain of bacteria grown on agar in a Petri dish.
Name one antibiotic other than streptomycin.
The scientist placed three paper discs containing different antibiotics (labelled P, Q, and R) onto the agar.
A student stated: "The bacterium is completely resistant to antibiotic Q."
Explain how the results shown in the diagram prove that the student is not correct.
Explain why the development of antibiotic-resistant bacterial strains poses a major global health risk.
Explain why viruses cannot be grown using a sterile nutrient broth or agar medium.
Explain why developing drugs that target and destroy viral pathogens inside the body is highly challenging.
