Both A & B T cells mature in: A Bone marrow B. Blood C. Thymus D. All of the above Antigens: A. Made by B-cells B. Made by T-cells C. Intiate immune response D. NoneExplanation / Answer
Answer:
1). D. Both A & B
A lymphocyte is one of the subtypes of white blood cell in a vertebrate's immune system. Lymphocytes include natural killer cells (NK cells) (which function in cell-mediated, cytotoxic innate immunity), T cells (for cell-mediated, cytotoxic adaptive immunity), and B cells (for humoral, antibody-driven adaptive immunity).
2). A. Defective or infected cells
Natural killer cells are white blood cells that can kill and contain cancer and infectious diseases.
3). B. T-Cell
HIV destroys part of the immune (say: ih-myoon) system. Specifically, it affects a type of white blood cell called the T lymphocyte (say: lim-foh-site), or T cell.
4). D. Both A & B
Each B cell produces a single species of antibody, each with a unique antigen-binding site and they mature in the bone marrow.
5). C. Thymus
T cells migrate to and mature in a distinct organ, called the thymus.
6). C. Innate immune response
Antigene is a toxin or other foreign substance which induces an immune response in the body, especially the production of antibodies.
