Answer to Question 1

ANS: D
The three embryologically distinct germinal tissue layers form all tissues and organs: endoderm, mesoderm, and ectoderm.

Answer to Question 2

ANS: D
Quantification of these phospholipids (the L/S ratio and PG concentration) provides a predictive index of the lung maturity in the fetus before birth and the risks of the development of respira-tory distress. For example, an L/S ratio of 2 or more indicates a relatively low risk for the devel-opment of respiratory distress syndrome while an L/S ratio of less than 1.5 is associated with a high risk. Conditions that lead to reduced fetal breathing and amniotic fluid formation (oligohy-dramnios) are linked to incomplete inflation of the lung with fluid and poorly developed (hypo-plastic) lungs.
