Organisms can be classified in the same species by morphology and ?

Geografical location and reproducing abilities.

If two organisms inhabit the same place (have the same habitat), together with some other important characteristics, they can be classified as the same species. The ability to reproduce is also an important characteristic, since members of the same species must be able to reproduce.

Hope it helped,

Happy homework/ study/ exam!

explanation:

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.
