Passage Hide
Cells obtain molecules needed to maintain homeostasis by using active transport to move molecules into the
cell or by synthesizing molecules within the cell. Cells also use active transport to remove toxins to maintain
intracellular homeostasis.
At the organism level, homeostasis is maintained in a variety of ways. For example, some organisms move
around their environment to locate food, water, and mates or to avoid danger.
Which statement correctly describes active transport, molecular synthesis, and movement?
Active transport, molecular synthesis, and movement all require energy
Active transport, molecular synthesis, and movement occur in all organisms.
Active transport and molecular synthesis occur in both plants and animals, but movement occurs only in
plants.
Active transport and molecular synthesis don't require energy, but movement does require energy.

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.
