Explain why quality of life is critically dependent upon energy use and consumption.

Research has shown that there is a direct relationship between the amount of energy used and overall economic activity in a country. in many ways quality of life is also directly related to the level of economic activity in a country because sufficient economic resources can ensure the physical components required for a high quality of life. in this way, energy use directly impacts quality of life by impacting economic activity.

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.
