Two next-door neighbours use very different strategies when it comes to landscaping their front yards. One neighbour plants a front lawn of lush green grass that requires regular watering and fertilizer application. The other neighbour uses stone pathways that wind through a variety of drought-resistant wild flowers and shrubs that are native to the area.
Explain why the drought-resistant wild flowers and native shrubs contribute more to the sustainability of a yard than does the lush green grass.

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.
