Question

Which of the following is true of both B cells and T cells?

They produce antibodies that attack pathogens.

They are nonspecific body defense systems.

They interact with antigen-presenting cells.

They have receptors on their surface that bind to antigens.

Answer 1

Answer:

Both B and T cells produce antibodies that attack pathogens

Answer 2

Answer:

-They have receptors on their surface that bind to antigens.

Explanation:

B and T cells are cells of specific immune system, which has ability to identify specific antigens and eliminate or inhibit their growth. B cells produce antibodies, while T cells produce cytokines during an immune response.

Both T cells and B cells receptors on their surface, known as BCR (B-cell receptor) and TCR (T-cell receptor). These surface receptors recognize and bind specific antigens present on pathogens and help the immune system to kill them.

Thus, the correct answer is 'last option.'
