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 \( A = \{-3, -2, -1, 0, 1, 2, 3\} \). A relation \( R \) is defined such that \( xRy \) if \( y = \max(x, 1) \). The number of elements required to make it reflexive is \( l \), the number of elements required to make it symmetric is \( m \), and the number of elements in the relation \( R \) is \( n \). Then the value of \( l + m + n \) is equal to:
For hydrogen-like species, which of the following graphs provides the most appropriate representation of \( E \) vs \( Z \) plot for a constant \( n \)?
[E : Energy of the stationary state, Z : atomic number, n = principal quantum number]
