Answer:
Lysozyme in saliva and tears.
Explanation:
Non- specific chemical defense is those chemical defense that is used to provide defense to the body against pathogens non-specifically because it does not use memory to select the pathogen.
One of the example of non-specific chemical barrier to infection is enzyme lysozymes that are present in saliva and tears. Lysozymes acts on peptidoglycan cell wall of gram-positive bacteria and provide non-specific defense against these gram-positive bacteria.
Other examples of non- specific chemical defense are hydrochloric acid in stomach, spermin in semen, etc. So lysozymes in saliva and tears are examples of nonspecific chemical defense.

- Prevalence refers to the total number of cases of hypertension at the point of time the survey happened.

- Prevalence is the right measure to use, because the total number of cases is what's wanted, not only the new cases.
- Race-specific prevalence has to be used instead of overall prevalence, because the two groups being compared are defined by race.
