Answer:
The shutting down of schools across the U.S is essential because although most children do not appear to suffer much when they contract the virus they can still spread it. Adults can be given instructions on how to prevent person-to-person transmission, and can be relied upon to follow those instructions to varying degrees, but it’s almost impossible to get children, especially younger ones, to do so.
Explanation:
Natural selection requires variation between individuals. Mutations and reproduction increase genetic variation in a population. Natural selection occurs when environmental pressures favor certain traits that are passed on to offspring.
The correct answer is compound.
The compounds comprise two or more elements, which are bonded together chemically, and can be dissociated, that is, distinguished by reforming and breaking the chemical bonds, by the decomposition reactions, like thermal decomposition or electrolysis. The process of decomposition generate simpler compounds or individual elements.

<span>The lungs are the main organ of the respiratory system, which carries oxygen through the body by means of red blood cells and picks up carbon dioxide, a waste gas, to expel from the body when an organism exhales. The trachea filters the inhaled air and branches into the bronchi, where the air tubes carry air directly into the lungs. The diaphragm is the main muscle of the respiratory system, contracting to increase the volume of the lungs and carry air into the body and expanding to force air out of the lungs.</span>
