d. Eosinophil
e. Red Blood Cell
b. IgG
An adaptive immune response directed against SARS-CoV-2
(the virus that causes COVID-19), but not closely related SARS-
CoV or MERS coronaviruses, would involve which of the
following molecules?
a. Membrane Attack a complex (MAC)
b. IgG
c. Complement

activating the classical complement pathway against
streptococcus pyogenes, a common bacterial pathogen that
, causes scarlet fever and other diseases
a. IgG
b. IgA
c. igD
d. IgM
e. IgE
c. High levels of IgM are circulating through their body and
neutralizing the virus
A patient had a primary exposure to influenza A two weeks ago
and is beginning to feel better. Which statement BEST describes
the humoral (antibody) immune response in this patient that is
helping them feel better?
a. High levels of IgG specific to influenza A are circulating
through their body and neutralizing the virus
b. Activated Th cells (aka helper T-cells) are releasing cytokines
activating Tc cells (aka cytotoxic T cells) to kill the virus
c. High levels of IgM are circulating through their body and
neutralizing the virus
d. Activated Tc cells circulating through their body and
destroying cells infected with the virus
e. New toll-like receptors (TLRs) evolved specifically to
recognize influenza A and release interferon
