Match List I with List II.
List I | Antimicrobials Names | List II | Names |
(A) | Narrow spectrum antibiotic | (I) | Furacin |
(B) | Antiseptic | (II) | Sulphur dioxide |
(C) | Disinfectants | (III) | Penicillin-G |
(D) | Broad spectrum antibiotic | (IV) | Chloramphenicol |
Choose the correct answer from the options given below:
• Narrow-spectrum antibiotics target specific bacteria (e.g., Penicillin-G).
• Broad-spectrum antibiotics target a wide range of bacteria (e.g., Chloramphenicol).
• Antiseptics are used for external applications to prevent infections.
• Disinfectants are stronger agents used to sterilize non-living surfaces.
- Narrow Spectrum Antibiotic (A): Penicillin-G is effective against a limited range of bacteria, making it a narrow-spectrum antibiotic. Match: (III).
- Antiseptic (B): Furacin is used for preventing infections in wounds and burns, making it an antiseptic. Match: (I).
- Disinfectants (C): Sulphur dioxide is used as a disinfectant for its antimicrobial properties. Match: (II).
- Broad Spectrum Antibiotic (D): Chloramphenicol is effective against a wide range of bacteria, making it a broad-spectrum antibiotic. Match: (IV).
Final Answer: (1)(A) – III, (B) – I, (C) – II, (D) – IV
Let one focus of the hyperbola $ \frac{x^2}{a^2} - \frac{y^2}{b^2} = 1 $ be at $ (\sqrt{10}, 0) $, and the corresponding directrix be $ x = \frac{\sqrt{10}}{2} $. If $ e $ and $ l $ are the eccentricity and the latus rectum respectively, then $ 9(e^2 + l) $ is equal to:
The largest $ n \in \mathbb{N} $ such that $ 3^n $ divides 50! is:
