Over a six-year period, a biologist has collected data about the physical characteristics, behavior, feeding habits and mating rituals of four bird species living in a South American rainforest. At the end of the six-year period, the biologist claims that evidence of evolution is present in two of the four species. Which of the following is most likely to occur when the biologist presents these findings to other scientists?

Scientists will revise the theory of evolution in light of this new discovery.

Explanation:

C Scientists will debate and seek confirmation through additional research prior to accepting the findings as fact.

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.
