The nurse is teaching fire safety to members of a community. when a community member asks which type of fire extinguisher would be appropriate to put out a bonfire, what will the nurse identify?

I would say that a bonfire would require a fire extinguisher that is specified for wood fires and that in order to put such a fire out, the extinguisher should  be aimed at the base of the flames until they are all put out.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
