The correct Answer is:
To solve the question, we will evaluate each statement one by one to determine which ones are correct. ### Step-by-Step Solution: 1. **Statement 1: Antacids and antiallergics work on different receptors.** - **Evaluation:** Antacids are used to neutralize stomach acidity and work primarily on proton receptors in the stomach. Antiallergics, on the other hand, work by blocking histamine receptors to alleviate allergic reactions. Since they target different receptors, this statement is **correct**. 2. **Statement 2: All drugs are medicines, but all medicines may not be drugs.** - **Evaluation:** This statement is true because while all drugs have medicinal properties, not all medicines are classified as drugs. For example, some medicines may contain excipients that aid in delivery but do not have therapeutic effects themselves. Thus, this statement is also **correct**. 3. **Statement 3: Agonists are drugs that mimic the natural messenger by switching on the receptor.** - **Evaluation:** Agonists indeed bind to receptors and activate them, mimicking the action of natural messengers (like hormones or neurotransmitters). This statement is therefore **correct**. 4. **Statement 4: Penicillin-G has a narrow spectrum antibiotic.** - **Evaluation:** Penicillin-G is known to be a narrow-spectrum antibiotic, effective primarily against specific types of bacteria. Therefore, this statement is also **correct**. ### Conclusion: All four statements are correct. ### Final Answer: 1. Correct 2. Correct 3. Correct 4. Correct
