Question 2
1. Women who have been blind since birth almost never
have breast cancer. A high level of one specific hormone
is though to contribute to their low cancer rate. Which
hormone is it and why are levels of this hormone
unusually high in the blind?
2. A diabetic who injects too much insulin can lose con-
sciousness. Explain how injecting excess insulin can
impair brain function. Explain also why an injection of
glucagon can restore normal function.
3. Endocrine disruptors can interfere with biological pro-
cesses by mimicking hormones, activating or blocking
the body's hormone receptors, disrupting the synthesis
hormones, or altering their breakdown. How are these
