Q1. What did germ theory help establish?
Germ theory linked particular microorganisms with disease, helping focus efforts on preventing and treating infections.

Q3. Which drug was an early treatment developed from sulfonamide research?
Prontosil was developed in the 1930s and led researchers to identify sulfanilamide as its active antibacterial compound.
Q4. What was important about the work of Florey, Chain, and their colleagues?
The Oxford team developed methods to purify and test penicillin, helping turn Fleming’s observation into a treatment.
Q5. What does antibiotic resistance describe?
Resistance is a trait of bacteria, not the patient. Resistant bacteria can survive treatment that would normally inhibit or kill susceptible bacteria.
Q6. Which statement about bacteria is most accurate?
Bacteria live in many environments, and many support normal body functions. Their effects depend on the organism, its location, and the person’s health.
Q7. Why are antibiotics not useful for treating influenza?
