Answer:

Gastric mucus forms a layer about one millimetre thick that lines the stomach, protecting the organ from highly acidic gastric juice and preventing the juice from digesting the stomach itself.

2....Antibodies are formed by a series of genes transcribed in B cells

3....The full form of BCG is the Bacillus Calmette-Guerin. It is a vaccination against tuberculosis
