Well, put this in your own words.

At plate boundaries, the tectonic plates rub against each other. They either slide over one another, causing earthquakes; or they smush into each other making mountains or valleys.

The right ventricle transports oxygenated blood to the lungs true or false

adell [148]

I believe the correct answer is FALSE.

<h2>Explanation:</h2>

The heart is an organ located at the center of the chest in the thoracic cavity and functions to supply blood to and from tissues giving the tissues oxygen and nutrients while taking away carbon dioxide and waste products. It is divided into 4 chambers and 2 chambers are separated by a muscular wall that prevents mixing of the blood.

<h2>Further Explanation:</h2>

Blood enters the heart via the vena cava which is divided into the superior vena cava that recieves blood from the upper region of the body that includes the head, neck and chest while the inferior vena cava recieves blood from the lower extremeties that includes the legs, the abdomen, the pelvic region and the thighs. The blood is deposited into the right atrium and is de-oxygenated. When it is deposited into the right atrium, the change in volume of the atrium and the expansion causes the valve to open and allow the de-oxygenated blood to flow into the right ventricle. The right ventricle then pumps the blood that is de-oxygenated to the lungs via the pulmonary artery which is the only artery that pumps de-oxygenated blood. In the lungs, carbon dioxide is removed and oxygen added to the blood and is taken to the left atrium which pumps the oxygenated blood to the left ventricle and then the left ventricle pumps the oxygenated blood to the rest of the body. The blood is then again taken through the body via the capillaries and the veins pick up the blood that has been removed of oxygen and added with carbon dioxide and transport the blood back to the heart via the vena cava. It enters the right atrium via both the inferior and superior vena cava and the de-oxygenated blood is circulated again to the lungs for oxygenation from the left ventricle.

A neuron with a cell body located in the CNS whose primary function is connecting neurons is called a ________.

brilliants [131]

Answer:

Intermediate neuron

Explanation:

Interneurons are the "middle man", neither a sensory or motor nueron, that creates neurial circuits, connecting a broad class of neurons in the spinal cord and brain. They enable communication from motor and sensory neurons in the central nervous systems and are classified into two groups; relay and local interneurons. Through neurial circuits, the brain is able to manage and deal with complex stuff such as decision-making and learning.
