Which of the following best describes an example of a nonspecific internal response to pathogens?

a. fever increases metabolism, speeding up the body’s reaction to the pathogens.
b. mucus traps the pathogens and prevents them from invading the body.
c. lymphocytes recognize the pathogens and destroy them.
d. dead skin cells provide a barrier between the pathogens and the body.

The correct answer is option A. Fever increases metabolism, speeding up the body’s reaction to the pathogens.

Explanation:

The non-specific immune response is an immediate response for any biological, chemical factors and pathogen-independent. It acts by secreting mucus, wax or other secreting and traps foreign Non-specific immunity is not forming any immunologic memory.

The nonspecific internal defenses include 3 main path that is phagocytic and natural killer cells, fever, and the inflammatory response. Fever increases the body temperature and metabolic process that speed up reaction or response against the pathogens.

Thus, the correct answer is option A. Fever increases metabolism, speeding up the body’s reaction to the pathogens

lets get this bread mom

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
