Answer: Oxygen atom has 8 Protons
Explanation:
Oxygen atom (O) has an atomic number of 8, and a mass number of 16.
Recall that atomic number of any element is equal to the number of protons in its electronic shell, hence, the number of protons in oxygen atom is also 8

The Moon, otherwise known as Luna, is the only natural satellite of Earth. It was created 4.6 billion years ago, and it is widely accepted that it was created when Earth collided with a planet-sized object called Theia. It’s the fifth-largest moon in our solar system and is the second brightest object in the sky (after the Sun).
Explanation:
History of The Moon
Called Luna by the Romans, Selene and Artemis by the Greeks, and many other names in other mythologies.
The Moon, of course, has been known since prehistoric times. It is the second brightest object in the sky after the Sun. As the Moon orbits around the Earth once per month, the angle between the Earth, the Moon and the Sun changes; we see this as the cycle of the Moon’s phases. The time between successive new moons is 29.5 days (709 hours), slightly different from the Moon’s orbital period (measured against the stars) since the Earth moves a significant distance in its orbit around the Sun in that time.
Answer:
<em><u>The diaphragm muscle contacts and relaxes to force the intake and expulsion of air from the lungs.</u></em>
Explanation:
The diaphragm is a large, dome-shaped skeletal muscle. It is very thin, and is located at the base of the chest just above the abdomen.
It plays a very important role during respiration or breathing by forcing the intake and expulsion of air from the lungs.
During inhalation, this muscle contracts, and flattens- in the process, a vacuum is created, effectively pulling air into the space. In exhalation the muscle relaxes, and is no longer flattened, this reduces the volume of the region, forcing air out of the lungs.
These contractions occur rhythmically and continuously.
