In higher latitudes where lakes freeze over in winter, how do cool autumn tempe]ratures fish make it through the winter? a-the cooling water slows fish metabolisms down and allows them to go into hibernation in winter. b-water from the bottom of the lake raises and provides oxygen to the cooler waters on the surface. c- cool water at the surface traps nutrients deep in the lake to provide food during the winter. d-the water in contact with the air sinks and mixes with the less oxygenated water in the deeper levels.

C- Cool water at the surface traps nutrients deep in the lake to provide food during the winter.

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.
