How does the cardiovascular system deliver nutrients and oxygen to all cells in the body via the flow of blood? Select all correct answers.

(The arteries carry blood away from the heart; the veins carry it back to the heart.)

(In the systemic circulation, the left ventricle pumps oxygen-rich blood into the aorta.)

(Veins contain a series of one-way valves that close to prevent the back flow of circulating blood.)

(Blood, which is low in oxygen, is collected in veins and travels to the right atrium and into the right ventricle.)

(The left ventricle pumps low-oxygen blood into the pulmonary artery, which branches off into smaller and smaller arteries and capillaries.)

(Carbon dioxide is released from the blood into the air via capillaries surrounding the heart.)

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.
