Which description indicates a portal of entry? - ANSWER-Body
features through which pathogens can enter host tissue
Pathogens produce proteins to prevent the fusion of the
phagosome and the lysosome (phagolysosome).
Why does this virulence factor facilitate invasion? - ANSWER-It
prevents the exposure of pathogens to lethal digestive enzymes.
Which action refers to a secondary infection? - ANSWER-An
infection by one pathogen enables another pathogen to cause an
infection.
What differentiates signs from symptoms of disease? - ANSWER-
Signs are measurable; symptoms are subjective.

Which procedure does a clinician use to measure a symptom? -

ANSWER-The period of illness stage
What defines the end of the incubation period for an infectious
disease? - ANSWER-The appearance of nonspecific signs or
symptoms of disease
How does the epidermis help prevent infection and disease? -
ANSWER-It provides a harsh environment for most pathogens
and periodically sheds.
How does the complement system contribute to the innate
immune response? - ANSWER-It is composed of proteins that
can be activated by the presence of pathogens to form the
membrane attack complex (MAC).

Why are antimicrobial peptides (AMPs) considered an innate
immune function? - ANSWER-AMPs are produced both routinely
and as a response to pathogens.
Which terms refer to monocytes when they differentiate into
tissue-specific phagocytes? - ANSWER-Macrophages and
dendritic cells
What is specifically being reported if the Centers for Disease
Control and Prevention reports 10,000 new cases of COVID-19? -
