Ted sensed that is became colder outside when clouds moved in front of the sun. How did he know that there was a change in temperature? O sensory receptors in his skin sent signals to his brain
O his eyes received visual cues and sent signals to his brain
O chemical cues from the air flowed into his body when he breathed
O his brain sensed changes in air temperature and sent messages to his brain​

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.

Can you put the picture?
