D. To examine how diseases are transmitted among populations
Answer: B
Rationale: Pharmacology focuses on how drugs act on biological systems and how the body responds. It bridges
chemistry, biology, and medicine to ensure safe and effective drug use.
2. Which ancient civilization is credited with first recording herbal remedies and using opium as pain relief?
