Question

Given below are two statements:
Statement I: Antibiotics are chemicals produced by microbes that kill other microbes.
Statement II: Antibodies are chemicals formed in body that eliminate microbes.
In the light of the above statements, choose the most appropriate answer from the options given below.

• A. Statement I is correct but Statement II is incorrect
• B. Statement I is incorrect but Statement II is correct
• C. Both Statement I and Statement II are correct
• D. Both Statement I and Statement II are incorrect

Answer 1

The Correct Option is C

To solve the question, let's evaluate each statement individually in the context of biological concepts:

1. Statement I: Antibiotics are chemicals produced by microbes that kill other microbes.
   • Antibiotics are indeed substances produced by certain microorganisms (like bacteria and fungi) that can destroy or inhibit the growth of other microorganisms. This is well-documented in microbiology as antibiotics play a crucial role in fighting bacterial infections.
   • Examples of antibiotics include penicillin, which was derived from the Penicillium fungi.
   • Conclusion: Statement I is correct.
2. Statement II: Antibodies are chemicals formed in the body that eliminate microbes.
   • Antibodies are proteins produced by the immune system, specifically by B cells, in response to foreign pathogens (such as bacteria, viruses, and other microbes).
   • They neutralize pathogens and prevent them from infecting cells, also marking them for destruction by other immune cells.
   • Thus, antibodies indeed play a critical role in identifying and eliminating microbes, supporting an adaptive immune response.
   • Conclusion: Statement II is correct.

Given this analysis, both statements correctly describe the roles of antibiotics and antibodies in microbial elimination. Thus, the correct answer is:

Both Statement I and Statement II are correct.
