A plant is placed in sunlight. The plant has one leaf marked A and one leaf marked B. Leaf A is covered with aluminum foil but leaf B is not. After five days, both leaves are removed from the plant. The amount of starch present in leaf A is compared to the amount of starch in leaf B. Which hypothesis is being tested in this investigation?

Explanation:

I don't understand bioligy

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.

i'm guessing this is from edg enuity so the answers would be, from top to bottom,
