Answer 1

Answer:

Antibiotics are used to treat or prevent some types of bacterial infection. They work by killing bacteria or preventing them from spreading.

Antibiotics are medicines that cannot kill viruses like the common cold, the flu, or COVID-19. Antibiotics fight bacteria, which are completely different from viruses in their structure and function.

Answer 2

Answer:

What are antibiotics:-

Antibiotics are medicines that fight infections caused by bacteria in humans and animals by either killing the bacteria or making it difficult for the bacteria to grow and multiply. Bacteria are germs. They live in the environment and all over the inside and outside of our bodies.

how antibiotics work :-

Antibiotics disrupt essential processes or structures in the bacterial cell. This either kills the bacterium or slows down bacterial growth. Depending on these effects an antibiotic is said to be bactericidal or bacteriostatic.

Why antibiotic penicillier has no effect on viruses:-

Viruses insert their genetic material into a human cell's DNA in order to reproduce. Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. The antibiotic has no “target” to attack in a virus.
