Hello! The answers are:

Explanation:

All of the statements in the questions are features of the cell theory.

Cell Theory:

The cell theory, proposed by scientists Theodor Schwann, Matthias Schleiden, and Rudolph Virchow, is the basic principle of biology. The cell theory contains three features or clauses that explain the basic structure and function of life. The cell theory postulates the following:

the correct answer would be 6 feet.

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.
