Chronic backache

<span>The nurse should provide preventive measures for chronic backache as a consequence of lordosis when caring for this client. Chloasma is characterized by darkened areas on the face, particularly over the nose and cheeks. It is also known as the mark of pregnancy. Chloasma is not caused by lordosis. Diastasis occurs as the pregnancy progresses when the rectus muscle stretches to the point that it separates. It is not caused by lordosis. Edema in lower extremities occurs due to an impeded venous return caused by pressure of growing fetus on pelvic and femoral areas. It is not caused by lordosis.</span>

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.

Chief cells are found in glands that line the inside of the stomach. These cells secrete large amounts of enzymes to aid in food
kvv77 [185]

The correct answer is: Endoplasmic reticulum.

One of the functions of the endoplasmic reticulum is transport of secretory proteins. Synthesized proteins are transported in vesicles to the Golgi apparatus.

Gastric chief cells have a high rate of enzyme secretion such as pepsinogen and gastric lipase. It is the cell also responsible for secretion of chymosin.
