Vaccines work
Vaccines contain disease-specific microbial strains that have been weakened or killed. When a vaccine is introduced into a healthy body, either orally or through injection, the body fights against the infection by producing suitable antibodies against the pathogen. These antibodies remain in the body, and the body also remembers how to fight when the same microbe enters the body again.
Farmers prefer to grow beans and peas in nitrogen-deficient soils.
Leguminous plants such as peas and beans have nitrogen-fixing bacteria called Rhizobium. Rhizobium present in the root nodules of leguminous plants helps in fixing atmospheric nitrogen and transforming it into nitrates and nitrites for plants' use. After harvesting, the roots are left in the soil, which results in the enrichment of the soil with nitrogen and increases its fertility. Therefore, farmers prefer to grow peas and beans in nitrogen-deficient soil.
What is food poisoning? Name the microorganism that causes it.
Illness from contaminated food; caused by Salmonella or Clostridium botulinum
