Differentiate the types of immunoglobulins. Please make a table.

Give the sequence of events from the time the B-cell encounters the antigen to actual antibody production.

Explain why IgM has a stronger power of agglutination than antibodies of any other class.

Six hours after admission the patient died. Based on data given, the patient had trapped, killed, and skinned 3 kit foxes, 4 coyotes, and 1 bobcat. The patient cut his left hand shortly before skinning…

Construct a typical antibody (immunoglobulin) molecule. Label the variable and constant regions, and the light and heavy chains.  Indicate which region determines the antibody’s isotype (class). Indicate which region determines its antigenic specificity.
