Where does the sugar we eat come from?

Sugar comes from either sugar cane or sugar beet with the climate of a geographical region being the prime influence on which is grown. In both cases, the juice is extracted from the sugar beet or cane and impurities are removed. It is then crystallised into white sugar, which is 99.95% sucrose.

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.
