Question

monique hasnt eaten since early this morning. it is now time for dinner. her stomach is growling, and she feels very hungry. one reason that she is feeling hungry is because her: blood glucose level has increased. ghrelin production is low. blood glucose level has dropped. leptin levels are high.

Explanation:

When blood glucose levels drop (due to not eating for a long - time), it triggers hunger. Ghrelin (hunger hormone) production would increase (not decrease) when hungry. Leptin (satiety hormone) levels would be low (not high) when hungry. An increase in blood glucose level would not cause hunger.

Answer:

blood glucose level has dropped.
