Problem:
rosabella was driving to her grandparents’ house with her family and they stopped to look at a lake on their way. above is a picture they took from where they stood outside their car, and the camera was pointed to the west. what time of day was it when they stopped to take this picture?

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

"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."
