A farmer who grows green beans lives in a area that experiences a lot of drought. Explain how he could use selective breeding to improve the chances of his bean plants surviving the droughts

The farmer could choose plants that lose less water, or store water more efficiently. He could then breed these plants together and repeat this process with the daughter plants, and their daughter plants, and so on.

This would make more plants with the chosen plants’ “good genes”, and therefore making more plants that can withstand drought.

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.
