7. hypothesis: this study proves that immune system needs to be trained by interaction with microbes.
9. ID: caused by 4 agents, infection, malnutrition, chemotherapy, radiation.
12. cause by under acitivity(hyposensitivity), and individual can lack T-cells or B-Cells, or both.
14. Involve atopy which is asthma and hay fever, and anaphylaxis fatal reaction.
15. 2: an example would be organs transplant, and Rh factors.

6. 4: This involves T-cells branch, and it's known as delayed sensitivity.
8. Cells: they carry cell receptors that bind to IgE and releases inflammatory cytokines.
10. 1 and 2 are important in recognizing self and regulating the immune response.
11. formed from mast cells, it stimulates eosinophils to release inflammatory cytokineas.
