Assertion: Antibiotics are effective against bacterial infection and not viral infection.
Reason: Viral diseases do not have their own body mechanism, but they use cells of the host.
Explanation:
Antibiotics are medications used to treat bacterial infections. They work by targeting specific components or processes in bacteria, either killing them directly or inhibiting their growth. However, antibiotics are not effective against viral infections.
Reasoning:
Viral diseases, such as the common cold, influenza, or COVID-19, are caused by viruses. Unlike bacteria, viruses are not considered living organisms as they lack their own cellular machinery for replication and metabolism. Instead, viruses rely on the host cells they infect to reproduce and carry out their life cycle.
When a virus infects a host cell, it takes over the cellular machinery of the host and uses it to replicate its own genetic material and produce more viral particles. Antibiotics, designed to target bacterial components or processes, are unable to effectively interfere with viral replication or disrupt viral particles.
Conclusion:
Therefore, the assertion that antibiotics are effective against bacterial infection and not viral infection is true. The reason provided, that viral diseases do not have their own body mechanism but use cells of the host, is also true and serves as the correct explanation for the assertion.
