Answer to Question 1

ANS: C
Normal human infants are immunologically immature when born, with deficiencies in antibody production, phagocytic activity, and complement activity, especially components of alternative pathways. They do not possess hypergammaglobuline mia. Possessing increased maternal IgG would not lead to recurring infections. The recurrent infections are due to decreased immunity, not maternal antibody breakdown.

Answer to Question 2

ANS: D
The liver is not a secondary lymph organ. The spleen, Peyer patches, and adenoids are secondary lymphoid organs.
