The correct answer is B) Federalism.
Dividing power between the state and national levels is known as "Federalism."
The framers believed in the principle of Federalism that is the system of government where power is divided between a central government and regional governments. The framers of the U.S. Constitution granted some faculties to the national government and granted others to the states.
The framers respected the states because they were already functioning one way or the other the people of that time were font to their states.
In other words, when we talk about United States politics, the principle of federalism refers to that the power of the government is shared by the state governments and the federal government.
This power functions under a system of checks and balances in which none of the branches of the government was more powerful than the other two. In the US government system, when federal law conflicts with state law, the federal law will win. This is included in the Constitution as the Supremacy Clause.
Sinoatrial node part of the autonomic nervous system adjusts the heart rate and the arteriole diameter to regulate blood pressure through negative feedback
The SA (sinoatrial) node is generates an electrical signal that can causes the upper heart of the chambers (atria) to contract. The signal and then passes through the AV (atrioventricular) node to the lower of the heart chambers (ventricles), causing them to contract, or to pump. The SA node is considered the pacemaker of heart.
The sinus node continuously generates electrical impulses, thereby setting the normal rhythm and also rate in a healthy heart. Hence, the SA node is also referred to as the natural pacemaker of the heart
