Hibernation
Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It most commonly occurs during winter months.

The term ______ refers to one-way “doors” that maintain blood flow in the proper direction.

Arteries

Valves

Cells

Veins

Valves
The aortic, tricuspid, pulmonary, and mitral valves are the four valves that open and close in time with your heart’s pumping action. Only one direction of blood flow is necessary for your heart to function correctly. That is made possible by the “in” and “out” valves in your heart, which have flaps to seal or open the valve.

Your heart is divided into how many chambers?

3

2

4

5

4
The right and left atria are the heart’s upper chambers. The heart also has two lower chambers (the right and left ventricles). The left side of your heart receives oxygen-rich blood from the lungs and sends it through the aorta to the rest of your body. The right side of your heart pumps oxygen-poor blood to your lungs.

A solar eclipse is what?

When the moon passes between Earth and the sun, blocking the sunlight from reaching Earth.
The moon casts two shadows on Earth during a solar eclipse. The umbra is the first shadow. As it approaches Earth, this shadow becomes smaller. It is the moon’s shadow’s deep center. The penumbra is the name for the second shadow. As it approaches Earth, the penumbra grows larger. People positioned in the shadow will be able to see a partial eclipse. Those who are in the umbra will be able to see a total eclipse.
