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.
Explanation:
The primary function of simple squamous epithelia is to facilitate diffusion of gases and small molecules.
<em>Highlighted </em><em>muscles </em><em>are </em><em>the </em><em>muscles </em><em>of </em><em>the </em><em>neck. </em><em>It </em><em>is </em><em>a </em><em>group </em><em>of </em><em>four </em><em>muscles </em><em>which </em><em>helps </em><em>to </em><em>stabilize </em><em>the </em><em>shoulder </em><em>joint. </em>
Semiconservative replication<span> would produce two copies that each contained one of the original strands and one new strand. Conservative </span>replication<span> would leave the two original template </span>DNA<span> strands together in a double helix and would produce a copy composed of two new strands containing all of the new </span>DNA<span> base pairs.</span>
The best estimate<span> for </span>Earth's age<span> is based on radiometric dating of fragments from the Canyon Diablo iron meteorite. From the fragments, </span>scientists calculated<span> the relative abundances of elements that formed as radioactive uranium decayed over billions of years.</span>
