Estradiol Is a Potent Stimulator of Vitellogenesis (Yolk Production)in Egg-Laying

Estradiol is a potent stimulator of vitellogenesis (yolk production) in egg-laying vertebrates.Increasing evidence suggests that many pollutants,for instance those derived from pulp mills,may mimic the actions of estradiol.If one were to place a sexually immature fish in water containing pulp mill effluents,what might you expect would occur?

A) The rate of vitellogenesis would decline.
B) The rate of vitellogenesis would increase.
C) The fish might reach sexual maturity sooner.
D) The rate of vitellogenesis would decline and the fish might reach sexual maturity sooner.
E) The rate of vitellogenesis would increase and the fish might reach sexual maturity sooner.
