Textbook Question
Chapter 6, Problem 5CRCAQ
Old Norse stories tell of a famous Viking named Egil, an actual person who lived
around A.D. 900. His skull was greatly enlarged and misshapen, and the cranial
bones were hardened and thickened (6 cm, or several inches, thick). After he died,
his skull was dug up, and it withstood the blow of an ax without damage. In life, he
had headaches from the pressure exerted by enlarged vertebrae on his spinal cord.
So much blood was diverted to his bones to support their extensive remodeling that
his �ngers and toes always felt cold, and his heart was damaged through overexertion.
What bone disorder did Egil probably have?

What are biofertilizers and mention the significance
PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.
How would increased estrogen affect the river otter population?
