Dr. Alvarez wanted to see if he had discovered a new element, so he analyzed his new element and performed an experiment to determine the element's density, melting point, and boiling point. Then, he repeated his experiment four more times before reporting his results in a scientific journal. Dr. Casey read Dr. Alvarez's report. Wanting to verify Dr. Alvarez's data, Dr. Casey repeated Dr. Alvarez's experiment three times, compared his results with Dr. Alvarez's results, and reported his own results in a scientific journal. Which of the following is an example of replication?

when Dr. Casey repeated Dr. Alvarez's experiment

Explanation:

I just did it on study island.

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.
