Answer to Question 1

Correct Answer: 3
Rationale: An antagonist occupies receptor sites, preventing them from being activated by the medication.

Answer to Question 2

Correct Answer: 2
Rationale: Since the LD50 is not ethical to determine in humans, the TD50 is used. The LD50 is used to determine adverse effects in humans, not efficacy or potency.
