44. Passive immunity differs from active immunity in that passive immunity results in the production of antibodies. involves the administration of preformed antibodies (produced outside the body) causes long-term immunity. results in the production of memory cells. is not effective against a preexisting condition.
15.In innate immunity, physical and chemical barriers serve as the human body's first line of defense. One of the chemical barriers is the sebum. How does the sebum function to protect the body from invasion and infection of pathogens? Note: This is a multiple question, choose the correct answer below: Sebum dilutes the number of microorganisms and washes the teeth and mouth. Sebum filters inhaled air by forming a trap for pathogens and dust. Sebum produces an acid that kills microorganisms in ingested food. Sebum provides a protective layer on the skin to inhibit growth of microorganisms.
