What is the function of interleukin-7 in lymphocyte formation? View Available Hint(s) Hint 1. Development of Lymphocyte Types  opened hint The different lymphocyte types are all derived from lymphatic stem cells.  Their ultimate fate depends upon the location where they mature and the signals that they receive.    What is the function of interleukin-7 in lymphocyte formation? It supports the differentiation of lymphoid stem cells into NK, B, and T cells. It supports the differentiation of pluripotential stem cells into lymphoid stem cells. It supports the differentiation of pluripotential stem cells into NK, B, and T cells. It supports the differentiation of lymphoid stem cells into NK cells and B cells.

16. The Type A Transferase enzyme, attaches N-acetylgalactosamine (GalNAc) to H-antigen epitopes; the Type B Transferase enzyme instead transfers galactose (Gal) to the H-antigen. Individuals with Type A blood thus have at minimum one copy of the active Type A Transferase, those with Type B have at minimum one copy of the active Type B Transferase, those with Type AB have one active copy of each, those with Type O have neither. Imagine an AB individual who acquires a mutation in their Type B Transferase gene that allows it to be active with either Gal or GalNAc. Make sure to include a brief justification for your answer to each question below. a. What blood type antigens would this individual express? b. If this individual had a child with a normal O partner, what possible blood type antigens could the child express? c. If this individual had a child with a homozygous dominant B partner (BB), what possible blood type antigens could the child express?
