As you learned in the previous research activity, homeostasis is one of the main characteristics of life. A normal body temperature for humans is approximately 98.6 degrees Fareinheit, or, 37 degrees Celcius. Use an online resource to look up the two mechanisms the human body uses to maintain a healthy body temperature. Describe how the body maintains homeostasis. (Hint: another way of thinking about this: What happens when the body gets too hot or too cold.) Different species have different adaptations. Spend a couple minutes researching why dogs pant. Explain how panting helps a dog maintain homeostasis.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
