Explanation:

Meteorite: Phenomenon of the sky that describes the light that occurs when a fragment of extraterrestrial matter enters Earth's atmosphere . Generally, a meteorite on the surface of any celestial body is an object that has come from another part of space. Meteorites have also been found on the Moon and Mars.

Meteorites that are recovered after being observed during their transit in the atmosphere are called "falls." The rest of the meteorites are known as "findings".

Respiration : Cellular respiration can be considered as a series of oxide-reduction reactions in which combustible molecules are gradually oxidized and degraded, releasing energy. Protons lost by food are captured by coenzymes. Breathing occurs in different cellular structures. The first of these is the glycolysis that occurs in the cytoplasm. The second stage will depend on the presence or absence of O2 in the medium, determining in the first case aerobic respiration (occurs in mitochondria), and in the second case anaerobic respiration or fermentation (occurs in the cytoplasm).

Photosynthesis : is a process whereby organisms with chlorophyll, such as plants, algae and some bacteria, capture energy in the form of light and transform it into chemical energy.

Pollution: It is the introduction of substances or other physical elements into a medium that causes it to be unsafe or unfit for use. The environment can be an ecosystem, a physical environment or a living being. The contaminant can be a chemical, energy (such as sound, heat, light or radioactivity).

Scattering: in physics, the phenomenon of wave separation of different frequency when passing through a material is called dispersion. All material media are more or less dispersive, and dispersion affects all waves; for example, to sound waves that travel through the atmosphere, to radio waves that pass through interstellar space or to light that passes through water, glass or air.

Meteoroid: minor body of the Solar System of approximately 100 µm to 50 m (maximum diameter). The upper limit of size, 50 m, is used to differentiate it from comets and asteroids, while the lower limit of size, 100 µm, is used to differentiate it from cosmic dust, however, size limits are not usually used very strictly being ambiguous the designation of objects that are close to these limits .

Spectrum : Electromagnetic Spectrum is a set of waves that range from waves with longer lengths such as radio waves, to those with shorter lengths like Gamma rays.  Between these two limits are: radio waves, microwaves, infrared, visible light, ultraviolet light and X-rays

The characteristics of each type of wave are not only their wavelength, but also their frequency and energy. Waves with a longer wavelength have a lower frequency and vice versa.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
