From the following, identify a speciﬁc component of the adaptive immune system that is formed in response to antigenic stimulation: A. Lysozyme
C. Commensal organisms
- Immunoglobulin is a speciﬁc part of the adaptive immune system and is formed only in response to a speciﬁc antigenic stimulation. Complement, lysozyme, and commensal organisms all act nonspeciﬁcally as a part of the adaptive immune system. These three components do not require any type of speciﬁc antigenic stimulation.
