The blood located in the heart’s left ventricle, which is rich in oxygen, travels through the aorta artery to the whole body, where the blood (coming from the arteries) gives oxygen and “food” to the capillaries and receives carbon dioxide and waste, which then (throughly the veins) travels back to the heart’s right atrium. Then, it goes from the heart’s right ventricle to the lungs, where it “gives” carbon dioxide and waste and receives oxygen, which then returns to the heart’s left atrium.
<u>Answer:</u>
<em>The exposure of sea bed or undersea surface is called sea-level regression.</em>
<u>Explanation:</u>
Sea-level regression occurs when sea level drops down due to several climatic changes. This triggers extinction of several species. There had been several mass extinctions in the past due to <em>sea-level regression.
</em>
<em>Chances of survival of shallow</em> water species become feeble when the sea level falls. In the case of mass extinctions regression can be seen as a symptom and not a cause.
Marine transgression is the opposite <em>phenomena of regression</em> where sea level rises and covers the land which was previously above the sea level.
