14. L.15.8 The table below summarizes the ideas and findings of scientists Scientist(s) Alexander Oparin Miller and Urey Contribution Hypothesized early life may have been formed in high heat environments, such as the sun or lightning strikes. Observed that gasses such as methane, ammonia, and hydrogen gasses react to produce amino acids when exposed to temperature fluctuations and electricity. Found that adding heat to solutions of amino acids produces primitive "protocells" Sidney Fox How does the work of these scientists contribute to the study of Biology?​

"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."

sodium i think the chemical element of atomic number 11, a soft silver-white reactive metal of the alkali metal group.
