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>.
There are choices for this question namely:
<span>a. 40% to 50%
b. 50% to 70%
c. 70% to 85%
d. 85% to 100%
The correct answer is 50% to 70%. Moderate-intensity activity is noted when a person reaches 50% to 70% of his or her maximum heart rate in exercise. The maximum heart rate is determined by subtracting the age to 220.
<em>For example, a 54-year-old male with type 2 diabetes needs to have moderate intensity activity. His maximum heart rate is (220-54) which is 166 bpm. 50% to 70% of 166 is 83-116 bpm. Therefore he should exercise and raise his heart rate at 83-116 bpm. </em>
