You are a substitute teacher in a high school biology lab class on the day the students are dissecting frogs. A particularly bright student happens to notice that the left adrenal gland is malformed in her frog. She asks if a problem in embryonic
development could have caused that. Although there may be more than one reason, what might you propose as an explanation based on embryonic development? What will be an ideal response?
