During the Paleocene-Eocene Thermal Maximum (PETM) 55.8 million years ago a significant amount of carbon was released into the ocean and atmosphere in a relatively short amount of time (less than 10,000 years). Based on the evidence from fossilized plant leaves in Bighorn Basin in Wyoming, which of the following happened in that region during the PETM? Select all that apply. Rainfall decreased

Air temperature increased

Air temperatures decreased

Plants with smooth-edged leaves which are better adapted to warmer climates became more abundant

Rainfall increased causing the forest in the region to convert to a sub-tropical rain forest

Astudent observes a star from two positions of earth in its orbit, in summer and winter, and measures the change in the position of the star. which of these can be best calculated by this method?

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.
