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 a line passing through the point $ (4,1,0) $ intersect the line $ L_1: \frac{x - 1}{2} = \frac{y - 2}{3} = \frac{z - 3}{4} $ at the point $ A(\alpha, \beta, \gamma) $ and the line $ L_2: x - 6 = y = -z + 4 $ at the point $ B(a, b, c) $. Then $ \begin{vmatrix} 1 & 0 & 1 \\ \alpha & \beta & \gamma \\ a & b & c \end{vmatrix} \text{ is equal to} $
