question 1 (1 point)\nwhich of the following is a barrier against pathogens provided by the skin?\na) high ph\nb) desiccation\nc) mucus\nd) tears

Answer

Brief Explanations:

The skin serves as a primary physical and chemical barrier in the innate immune system. Desiccation (drying out) is a key mechanism because most pathogens require a moist environment to survive and proliferate. The skin's surface is naturally dry, which inhibits the growth of many microorganisms. Regarding the other options: the skin actually has a low (acidic) pH rather than a high one; mucus is produced by mucous membranes, not the outer skin; and tears are produced by lacrimal glands for the eyes.

Answer:

b) desiccation
