_ proteins are produced by WBC in response to _ and provide immunity?
Correct answer: D. Antibodies, antigen
- A. Antibiotics, antigen
- B. Antibodies, RBC
- C. Globulin, histamine
- D. Antibodies, antigen
Explanation
Antibodies, also known as immunoglobulins, are proteins produced by white blood cells in response to antigens, and they play a crucial role in providing immunity. Antigens are foreign substances that trigger an immune response. Antibodies bind to specific antigens to neutralize or eliminate them, providing immunity against diseases.

About Specific Defense Mechanism
Specific defense mechanisms provide targeted immunity through B lymphocytes, T lymphocytes, antibodies and memory cells that recognize particular antigens. Questions cover humoral and cell mediated responses, clonal selection, primary and secondary immune responses, vaccination and passive immunity, while distinguishing adaptive defenses from the immediate, non specific innate response.
