Will frogs exposed to the hormone estrogen lay more eggs?

Yes

Explanation:

A female frog is able to lay eggs only when the level of estrogen is at the highest level in the body. However both male and female release sperm and egg simultaneously at the same time in order to induce high mating probability. Both male and female acquire a mating posture known as as amplexus which enhances the level of estrogen in females and they thus release their egg .

true is the answer : )

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
