Which phase of the cell cycle best describes a cell that has exited from active cell division and remains indefinitely with each chromosome consisting of a single chromatid?

Answer;

- G0 -phase

Explanation;

-The G0 phase is a period in the cell cycle in which cells exist in a quiescent state. G0 phase is viewed as either an extended G1 phase, where the cell is neither dividing nor preparing to divide, or a distinct quiescent stage that occurs outside of the cell cycle.

A cell that has exited from the cell cycle is in G0 phase. This phase is similar to G1 in that each chromosome consists of a single chromatid as the chromosomes have not undergone DNA replication.

A cell in G0 can remain in this phase of the cell cycle indefinitely. The difference between G1 and G0 is that a cell in G1 is actively preparing to enter S phase.

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.

i'm guessing this is from edg enuity so the answers would be, from top to bottom,
