Protists are very diverse, and many different classification schemes have been used to define relationships between the protists. traditionally, protists have been classified by their source of energy and nutrients, whereas newer classification schemes use mode of locomotion. how are amoeboids classified using both of these schemes?

answer: c. two haploid cells

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.
