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

Answer:
Federalism is the system where sovereignty is constitutionally divided between a central governing authority and constituent units.
Explanation:
Federalism is the system of government in which sovereignty is constitutionally divided between a central governing authority and constituent political units. It is based upon democratic rules and institutions in which the power to govern is shared between national and state governments, creating a federation. Dual federalism is a political arrangement in which power is divided between national and state governments in clearly defined terms, with state governments exercising those powers accorded to them without interference from the national government. Dual federalism is defined in contrast to cooperative federalism, in which national and state governments collaborate on policy. Dual and cooperative federalism are also known as ‘layer-cake’ and ‘marble cake’ federalism, respectively, due to the distinct layers of layer cake and the more muddled appearance of marble cake.
Federalism was the most influential political movement arising out of discontent with the Articles of Confederation, which focused on limiting the authority of the federal government. The movement was greatly strengthened by the reaction to Shays’ Rebellion of 1786-1787, which was an armed uprising of farmers in western Massachusetts. The rebellion was fueled by a poor economy that was created, in part, by the inability of the federal government to deal effectively with the debt from the American Revolution. Moreover, the federal government had proven incapable of raising an army to quell the rebellion, so Massachusetts was forced to raise its own.
The most forceful defense of the new Constitution was The Federalist Papers , a compilation of 85 anonymous essays published in New York City to convince the people of the state to vote for ratification. These articles, written by Alexander Hamilton and James Madison, examined the benefits of the new Constitution and analyzed the political theory and function behind the various articles of the Constitution. Those opposed to the new Constitution became known as the Anti-Federalists. They were generally local, rather than cosmopolitan, in perspective, oriented toward plantations and farms rather than commerce or finance, and wanted strong state governments with a weaker national government. The Anti-Federalists believed that the legislative branch had too much unchecked power, that the executive branch had too much power, and that there was no check on the chief executive. They also believed that a Bill of Rights should be coupled with the Constitution to prevent a dictator from exploiting citizens. The Federalists argued that it was impossible to list all the rights and that those not listed could be easily overlooked because they were not in the official bill of rights.
Answer:
The correct answer is: Freud formulated his views based on careful observation of children.
Explanation:
Freud indeed saw the mother-infant relation as the prototype around which all later close relationships revolve, in fact, Freud proposes that neurosis later emerge in life as a result of many factors including an insatisfactory or pathological relationship of the infant with the first object (the mother).
Freud also claimed that the mother-infant relationship was the most important one and that mentally healthy adults usually had a healthy mother-infant relationship.
Freud also focused on the importance of breastfeeding as a source of oral gratification during the conceptualizations of the psychosexual stages of development.
However....
Freud didn't perform any type of systematic or careful observation of children during the development of his theories.

Answer:
Limited convertibility
Explanation:
Limited Convertibility refers to a situation in which government regulations prevent the free conversion of the home currency into a foreign one. Because the government is only able to regulate currency transactions within its borders, foreigners are still able to trade the currency. Only residents are unable to convert a currency with limited convertibility.
Countries that are in the process of moving to a more open economy may need to open up currency restrictions in steps rather than all at once. This has been the case in the development of countries that once had centrally planned economies, as opening up domestic markets would subject the home market to foreign competition.
