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?​

Taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? view available hint(s)taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? the enzyme will not work on human dna.nothing should be altered.the ph should be decreased.the temperature should be raised.
