The return of blood to the heart is assisted by the action of the skeletal- muscle pump. As muscles move, they squeeze the veins running through them. Veins contain a series of one-way valves, and they are squeezed, blood is pushed through the valves, which then close to prevent backflow.
Answer:
C) Both are waves of energy, but ultraviolet waves cannot be seen.
Explanation:
Both visible light and ultraviolet are two manifestations of the same thing: electromagnetic radiation (which is, basically, energy in one of its forms). They both travel empty space as waves, but visible light has a longer wavelength, which means that the distance between succesive peaks of the wave is larger than that of ultraviolet radiation. Visible light just happens to have a wavelength in the range our eyes are capable of seeing, but ultraviolet has a shorter wavelength than that, therefore we cannot see it.
Answer:
The correct answer would be bones.
X-rays are high energy electromagnetic waves which have an ability to penetrate most of the biological tissues.
In the X-ray machine, a beam of high energy X-rays is passed through the filters and subject and then fall on the detector or photographic film to produce X-ray.
Dense tissues like bone, teeth, tumors et cetera blocks or stops most of the X-ray particles from reaching the detector or photographic film.
It forms glowing pictures on the X-ray film or photographic film.
The denser the material the brighter the image will be formed on the photographic film.
