Answer:
C. ultraviolet radiation.
Explanation:
Cell injury occurs when cells undergo specific changes when subjected to an internal factor or an external factor. Such change causes "illness" to the person.
Under<em> "toxic injury," </em>two sources may cause an injury to the cell. These are <em>endogenous and exogenous factors. </em>Endogenous factors originate within the body while the exogenous factors originate from the environment.
Among the choices above, it is only the<em> ultraviolet radiation</em> that is considered an exogenous factor because it originates from outside the person's body. <u>Prolonged exposure to UV light damages the cells</u> which can lead to <em>cancer</em>.
I'm not entirely sure but I think this is true (?) because rescue breathing should only be used if any of the following happened to the victim: drowning, drug overdose, collapse due to breathing problems, an unresponsiveness in infants or children, an unconsciousness adult that isn't breathing normally, and if they are having prolonged cardiac arrest.
Hope this helps! :)
