Which of these true statements could contribute to a plausible hypothesis for why the alternation of generations evolved in the earliest land plants? Select all that apply. Gametophytes lack the ability to form rigid (lignified) vascular tissues. It allowed one generation to specialize in fertilization and the other in dispersal. The biopolymer sporopollenin first evolved to protect the diploid stage of green algae. Many gametophytes tolerate desiccation.

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.
