Suppose you are performing an experiment in which you must use heat to denature a double helix and create two single stranded pieces. based on what you know about nucleotide bonding, do you think the nucleotides will all denature at the same time? use scientific reasoning to explain why.

i think that d. wind is the answer.   i missed the question when i answered a. currents.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
