During which phase of cell cycle do chromatids form

Explanation:

a full set of sister chromatides us created during the synthesis (S) phase of interphase , when all the chromosomes in a cell are replicated the two sister chromatides are seperated from each other two different cells during mitosis or during the second division of meiosis

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 think the answer is g1
