The answer is "it controls the rate of breathing by sending hormones through the blood." (A)

For example, this quote states that "The response of the brainstem to increased levels of carbon dioxide in the blood is coordinated with the response of the cardiovascular system. When these chemoreceptors detect such a change, the body responds by regulating blood flow and breathing."

How do magnetic stripes of iron in ocean rock provide evidence of seafloor spreading
STatiana [176]

Answer:

In the 1960s, scientists found evidence that new material is indeed erupting along mid-ocean ridges. The scientists dived to the ocean floor in Alvin, a small submarine built to withstand the crushing pressures four kilometers down in the ocean. In a ridge’s central valley, Alvin’s crew found strange rocks shaped like pillows or like toothpaste squeezed from a tube. Such rocks form only when molten material hardens quickly after erupting under water. These rocks showed that molten material has erupted again and again along the mid-ocean ridge.

When scientists studied patterns in the rocks of the ocean floor, they found more support for sea-floor spreading. You read earlier that Earth behaves like a giant magnet, with a north pole and a south pole. Surprisingly, Earth’s magnetic poles have reversed themselves many times during Earth’s history. The last reversal happened 780,000 years ago. If the magnetic poles suddenly reversed themselves today, you would find that your compass needle points south.

Explanation:

I found this somewhere.
