Answer to Question 1

ANS: A, C, D
When researchers sought to investigate how exposure to famine in utero had impacted individu-als born in a historically prosperous country whose nutritional intake was dramatically impacted by WWII, they found that individuals who suffered nutritional deprivation in utero were more likely to suffer from obesity and diabetes as adults than individuals who had not experienced nutritional deprivation during gestation. Other data sets reveal elevated risk of cardiovascular and metabolic disease for offspring of individuals exposed during early development to fluctua-tions in agricultural yields. The research does support the development of asthma or Crohn's dis-ease.

Answer to Question 2

ANS: B
Atrophy is a decrease or shrinkage in cellular size. Hyperplasia is an increase in the number of cells. Vacuoles are membrane-bound vesicles within the cell that contain cellular debris and hy-drolytic enzymes. Lipofuscin is the yellow-brown age pigment.
