A car was travelling at a speed of 25m/s northbound on the 15fwy. Suddenly the driver sees that the onramp to the 215 fwy eastbound was approaching and the driver was afraid they may miss the onramp. The driver accelerates for 5 seconds to a speed of 30m/s to change lanes so they would not miss the onramp to the 215fwy. What was the rate of acceleration when the driver was changing lanes to not miss the onramp to the 215fwy? Explain how you found your answer and include units.

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.
