Not very effective at preventing intruders

Detailed explanation-1: -The cells and molecules of innate immunity are rapidly activated by encounter with microbes or other “danger signals.” The rapidity of the response is essential because of the fast doubling time of typical bacteria.
Detailed explanation-2: -Innate immune responses are not specific to a particular pathogen in the way that the adaptive immune responses are. They depend on a group of proteins and phagocytic cells that recognize conserved features of pathogens and become quickly activated to help destroy invaders.
Detailed explanation-3: -Innate, or nonspecific, immunity is the defense system with which you were born. It protects you against all antigens. Innate immunity involves barriers that keep harmful materials from entering your body. These barriers form the first line of defense in the immune response.
Detailed explanation-4: -1. What is not required in the innate immune responses? Explanation: In innate immune responses, prior encounter with the microbe is not required. The innate immune responses provide the body with first line of defense.
