If the amount of sodium in the blood increases, what would a negative feedback control mechanism be expected to do?
Crank

Answer: Decreases

Explanation:

The amount of sodium in the blood will increase as the main function of the negative feedback is to maintain the homeostasis inside the body.

If blood pressure is too high, then heart rate decreases because of this the blood vessels increases in the diameter and the kidney retains less water.

These changes will return the blood pressure to be normal. The same process gets reversed when the blood pressure decreases.
