What is your abi? what does this value tell you about your risk of peripheral artery disease?

ABI means Ankle-Brachial Index. ABI is a test used to diagnose peripheral artery disease. The ABI compares blood pressure in the ankle to blood pressure in the arm, shows how well blood is flowing in the limbs and indicates if there is any or no blockage or rigid arteries. The amount of blockage establishes the level of peripheral artery disease.

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.

Phoenix [80]

Answer:

SER, they are capable of synthesizing testosterone of Adrenocortical cells.

Explanation:

Adrenal smooth microsomal cells are  enriched in smooth endoplasmic reticulum SER, membranes of which contain high levels of translocation apparatus and oligosaccharyltransferase complex proteins. STEROID-SECRETING CELLS are characterized by abundant smooth endoplasmic reticulum (SER). These cells synthesize cholesterol as a precursor for steroid hormones or take up this substrate from plasma lipoproteins. Many of the enzymes for sterol and steroid synthesis are localized in the smooth-surfaced endoplasmic reticulum. This organelle is particularly prominent in cells of the inner zones of the adrenal and fluctuates in amount and configuration in response to hormonal stimulation and sterol levels.

What is an event of a convention current in the air
Effectus [21]

Answer:

Convection drives the circulation of air in the earth’s atmosphere. The sun heats the air near the earth’s equator, which becomes less dense and rises upward. As it rises, it cools and becomes less dense than the air around it, spreading out and descending toward the equator again.
