The genetic code is essentially the same for all organisms. from this, one can logically assume which of the following?
a) a gene from an organism can theoretically be expressed by any other organism.
b) all organisms have experienced convergent evolution.
c) dna was the first genetic material.
d) the same codons in different organisms translate into the different amino acids.
e) different organisms have different numbers of different types of amino acids.

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.
