Refer to Figure 45.8, below. Which of the statements below about foraging behavior is NOT correct?

A) Levels of for mRNA are significantly higher in foragers compared to nurses.
B) cGMP and cAMP, cyclic nucleotides, were used as activators of cGMP-dependent protein kinase.
C) cGMP but not cAMP was capable of activating kinase in nurse bees who then showed a significant increase in foraging behavior.
D) cAMP was capable of activating a kinase that increased nurse bee behavior in foragers.
E) The increase in nurse bee foraging was directly related to the dose of cGMP.
