1. Why does the moon go through Phases?
liq [111]

Explanation:

1.The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. The Moon spends the extra 2.2 days "catching up" because Earth travels about 45 million miles around the Sun during the time the Moon completes one orbit around Earth.

2.

An eclipse is the result of the total or partial masking of a celestial body by another along an observer's line of sight. Solar eclipses result from the Moon blocking the Sun relative to the Earth; thus Earth, Moon and Sun all lie on a line. Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line. In this case the Earth's shadow hides the Moon from view.Lunar and solar eclipses occur with about equal frequency. Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse. As a result, you are more likely to see a lunar eclipse than a solar eclipse.

3.Why Do We have Seasons?

As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected. Since the tilt of the axis is 23 1/2 degrees, the North Pole never points directly at the Sun, but on the summer solstice it points as close as it can, and on the winter solstice as far as it can.

Why Do the Seasons Change on Earth?

Two things cause the seasons to change. First, the Earth moves around the Sun. Second, the Earth has a tilted axis of rotation.

The Earth spins around an axis. This imaginary line extends from the South Pole to the North Pole. But the Earth’s axis is not vertical. It’s actually tilted at an angle of 23.5°. The planet is always tilted in the same direction as it orbits the Sun.

What is the main sugar used by cells for energy?
butalik [34]

Answer:

The answer is GLUCOSE.

Explanation:

Glucose is the main sugar used by cells for energy. Glucose is derived from the digestion of carbohydrates. In humans, glucose is usually absorbed into the blood from the small intestine, the blood then carry the blood around the body, allowing each cell to have access to the glucose it needs.

If the quantity of glucose in the blood is more than needed per time, the body usually store the excess glucose as glycogen, the glycogen will be turned to glucose and release for cell use when the quantity of sugar in the blood is low. In the absence of glycogen, other macro nutrients such as lipids and proteins can also be converted to glucose via gluconeogenesis when the concentration of glucose in the blood is low.

The cells oxidize the glucose and convert it to energy in form of ATP, which they use to carry out their life activities.
