The diagram is a model of one way that materials move across the cell membrane. oxygen molecules are represented by two red circles. carbon dioxide molecules are represented by a gray circle with two red circles attached. the left hand side of the diagram shows the beginning concentrations of the two types of molecules. the right hand sides shows how the molecules have moved over time. which sentence best explains the movement of oxygen molecules over time? a. they move to an area with a higher oxygen concentration b. they merge with the cell membrane to form vacuoles c. they move to an area with lower oxygen concentration d. they become transport proteins in the cell membrane

How can a geological time scale best be reconstructed? a) comparing vestigial structures in living species b) comparing homologous structures in living species c) examining homologous structures in fossil remains d) examining the written records of scientists from past cultures

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.

Which example would the nurse consider to be a part of systems thinking theory?
