Answer:
The body requires sun to make vitamin D (option b)
Explanation:
Vitamin D is a nutrient belonging to the liposoluble vitamins —together with vitamins A, E and K— that participates mainly in the metabolism and homeostasis of calcium and phosphorus, among other functions.
<em><u>Dehydrocholesterol</u></em><em><u> is the chemical compound from which </u></em><em><u>vitamin D₃</u></em><em><u> —cholecalciferol— is synthesized, which occurs in the skin thanks to the effect of </u></em><em><u>sunlight</u></em><em><u>.
</u></em>
Cholecalciferol is inactive, and as it passes through the liver and kidney it is transformed into its active equivalents, calcidiol and calcitriol, respectively.
Given what we know about the principles of training, we can confirm that option B includes an option that is not a principle of training.
<h3>What are the principles of training?</h3>
The five principles of training are:
- Specificity
- Progression
- Overload
- Reversibility
- Tedium
Option B includes the word sport, which is not mentioned as one of the five principles of training since it actually includes all of them within the action itself.
Therefore, since "sport" is not a principle of training, we can confirm that option B is the correct choice for this question.
