Question

what is the difference between b - cell lymphocytes and t - cell lymphocytes?
b cells regulate blood ph, and t cells regulate body temperature.
b cells are produced in the thymus, and t cells are produced in the bone marrow.
b cells engulf bacteria, and t cells carry bacteria to the lymph nodes.
b cells produce antibodies, and t cells destroy infected cells.

Explanation:

B - células producen anticuerpos para neutralizar antígenos. T - células (especialmente citotóxicas) identifican y destruyen células infectadas por virus u otras patógenos. Las otras opciones son incorrectas: B y T células no regulan pH sanguíneo o temperatura corporal (opción A), B células se producen en la médula ósea y T células en el timo (opción B), y fagocitosis es función de macrófagos, no de B o T células (opción C).

Answer:

D. B cells produce antibodies, and T cells destroy infected cells.
