• D. Statement 1: False; Statement 2: False

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.
e.g., Streptomycin, Penicillin etc.
Vaccines are ineffective against viruses as they lack cell walls. They are composed of dead or weakened pathogens which stimulates our immune system to produce antibodies against pathogen.
