Which of the following best describes a difference between the nonspecific and specific immune responses? a. the nonspecific response is based only on physical barriers, while the specific response includes both physical and chemical barriers. b. the nonspecific response provides a lasting immunity from previously encountered pathogens, while the specific response does not. c. the nonspecific response provides an immediate response, while the specific response involves a delay between exposure and response. d. the nonspecific response relies on the recognition of pathogens to combat infections, while the specific response relies on inflammation.

The correct answer is C. 

(The nonspecific response provides an immediate response, while the specific response involves a delay between exposure and response.)

 - The non-specific immune response is the first line of protection from different types of pathogens and microbes such as skin (physical barrier). It is immediate response however, it is not specifics and it does not involve the recognition of pathogens.

- The specific immune response depends on pathogen recognition and therefore is long-lasting immunity and it takes time to be effective. This response includes B- cells, T-cells, phagocytic cells and NK cells.

equal distribution i think.

b is the correct answer
