Which of the following is not a property of b cells? select one: a. produce plasma cells and memory cells b. low numbers circulating in the blood c. require antigen presented with mhc proteins d. receptors called immunoglobins e. mature in the bone marrow

The answer option that is not a property of the B cells is C, 'requires antigen presented with MHC'. B cells do not require MHC to recognize the antigen.

Explanation:

Major Histocompactibility Complex (MHC) is a genetic entity that encodes proteins that is necessary for the recognition of antigens by a set of immune system that is acquired such as the T cells. The MHC does this by exposing the antigens on the surface of the cell for easy recognition by the T cells. The B cells do not require such protein, it can recognize its antigens in their original form. All other options are accurate concerning B cells.

the answer is b: 1.4 km/hr
