Answer:
b. They are produced by memory B cells
Explanation:
The rapid cell division in activated B cells is followed by the differentiation of daughter cells into the plasma cells. The plasma cells are the precursor for antibodies and memory B cells. The antibodies kill the antigens while memory B cells are long-lived cells.
Hence, antibodies are not produced by memory B cells but by plasma cells.
There are 2 functions for cell surface markers. The first is to recognize the outside cell. The second is to allow the cell to bind to substances outside the cell.
Cell surface markers are proteins expressed on the surface of cells that often conveniently serve as markers of specific cell types. There are different types of cell surface markers. These markers are vital for the human body to function. These markers also vitally affect the functions of other biological systems of other organisms and creatures such as animals.
