antigens can trigger an immune response. is this a specific or a nonspecific defense? explain.

Specific Defense

Explanation:

Specific immune system gets activated when the pathogens (foreign elements) enter the body and are able enough to bypass the innate immune defenses thereby activating the adaptive immune system  

Specific defense is triggered by elements found on the surface of pathogens. These surface elements are called antigens. Antigens responds to these pathogens by producing antibodies specific to pathogen surface type.
