Answer:
Ozone (O₃) gas
Explanation:
In the Earth's stratosphere, oxygen gas (O₂) is combined with atomic oxygen (O) to form ozone gas (O₃). This is very important because ozone protects the life on Earth from ultraviolet (UV) radiation from the Sun. UV radiation is high-energy radiation, and it is very dangerous for living organisms. Ozone molecule (O₃) absorbs UV radiation and it breaks down by forming O₂ and atomic oxygen (O) again. In this way, it protects the Earth from nocive radiation.

2. a liquid that acts to dissolve or suspend substances - solvent
3. a chemical compound that doesn't contain carbon - inorganic
4. a substance that is dissolved in a liquid - solute.
Explanation: Organic compounds are compounds that contain carbon, and mostly contain hydrogen.
Inorganic compounds are compounds that do not contain carbon.
A solute is a substance which is present in smaller proportions and dissolves or suspends in a liquid called solvent, which is present in larger proportions. The solute and the solvent together form a solution.
