Answer #1

. 1.Which type of antibodies are present in the blood of a person with type O, Rh- blood?

As antigen O is present so it will have antibody A and antibody B.

Antibody D.

2. Immunosuppressive medications such as cyclosporin A and tacrolimus suppress cellular-signaling mechanisms in?.

Both regulate T cells. They inhibit T cell proliferation.

So, the correct answer is b.

They do not inhibit mast cells or all WBC. They do not inhibit B lymphocytes.

3. Autoimmunity involved IgE and IgG.

Both of them are involved in autoimmunity.
