*From the following, identify a specific component of the adaptive immune system that is formed in response to antigenic stimulation: A. Lysozyme B. Complement C. Commensal organisms D. Immunoglobulin correct answer: *D. Immunoglobulin is a specific part of the adaptive immune system and is formed only in response to a specific antigenic stimulation.
