Scenario 1: A river in North Carolina has been tested and the following data is obtained:
pH = 7.1
Dissolved Oxygen = 7 mg/L
Nitrates = 8 mg/L
Phosphates = 0.03 mg/L
Biotic Index = 3.5
What is the overall quality of this river? How do you know? If the quality is low, what do you think could be happening in the environment to cause these readings?

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.
