What is the likely evolutionary effect on a species of an increase in global temperatures over time?

The evolutionary effect on a species of an increase in temperature may be in come into two. The first is that the species may become adaptive to the change by developing specific organs that allow itself to cool off. However, if the increase in global temperature is too much for a certain species to handle, it may be become extinct. 

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.
