PLEASE HELP I WILL MARK AS BRAINLIST FW.02]Which of these best matches surface features with the processes that are responsible for their formation?
O sinkholes, caves, and hills heating of ground water due to geothermal energy
Ogeysers, hills, sinkholes groundwater erosion leading to deposition of minerals
O sinkholes, caves, and hot springs chemical and physical actions of groundwater
geysers, sinkholes, and hot springs dripping of groundwater from the ceiling of an underground cave

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.
