The complement system of defense is composed of proteins that are always present in the blood. Which statement describes the importance of this system in early pathogen defense? A.) It does not have to be activated by antibodies. B.) It rapidly lower the blood pH. C.) It recognizes specific common pathogens. D.) It causes immediate pathogen lysis.

Adaptive immunity includes which of the following processes?   Question 2 options:   A)  phagocytosis   B)  inflammation   C)  production of antibody   D)  production of interferon

Match the types of immunity written on the table with the descriptions below. Write the number corresponding to the type. 1. Innate 3. Natural-active 5. Natural- passive 7. Antibody-mediated 2. Acquired Adaptive 4. Artificial-active 6. Artificial-passive 8. Cell-mediated 1. The body is producing antibodies as a result of bacterial infection. 2.
