The correct answer is letter A: the circulatory system removes waste from the tissues by converting carbon dioxide-rich blood into oxygen-rich blood that can be circulated throughout the body to support its several functions. Without the lungs the human body will not be able to process converting blood cells into oxygen-rich cells in the body.
The answer is probably air.
Asynchronous Learning is when each student works at their own pace, and may not collaborate on work in class meetings, so the correct answer here would be D!
Answer: Increased concentration of glucose in leaf cells
Explanation:
Based off the flowchart, the process that it's describing is photosynthesis because during this process sunlight and CO2 are taken in by a plant to produce glucose. If we are exposed to sunlight and are increasing the use of CO2, then there must be a higher concentration of glucose in the leaf cells. Glucose is a product of photosynthesis.
Answer: from the pulmonary veins into the left atrium.
Explanation:
After oxygenation of blood in the lungs, the right and left pulmonary veins carry oxygenated blood and empties it into the left atrium. The left atrium then empties the blood into the left ventricle through the left atrioventricular valve.
With contraction, the ventricle pumps the blood to the systemic circulation through the aorta. The blood flow into the aorta is guarded by the aortic valve.
