Answer 1

The correct option is B Statement 1- True, Statement 2- False

Antibiotics are chemicals extracted from some microorganisms to kill other microorganisms. They act by blocking the biochemical pathways responsible for synthesis of cell wall. Viruses do not possess any cell wall and the genetic component is present inside the protein coat. This is the reason why antibiotics are not effective against viruses.
E.g. Streptomycin, Penicillin, etc.

A vaccine is an antigenic substance that develops immunity against a disease which can be delivered through needle injections or by mouth or by aerosol. They are composed of dead or weakened pathogens which stimulates our immune system to produce antibodies against pathogen.
E.g. Polio vaccine, Hepatitis B vaccine, etc.
