Derrick has a vitamin D deficiency. Hypothesize an explanation for why he may have this deficiency
What will be an ideal response?
Derrick may not spend enough time in the sun, exposed to UV light. Vitamin D is made by the skin in response to exposure to UV light. Vitamin D increases calcium ion absorption in the intestines. Without vitamin D, Derrick may have inadequate bone deposition due to lack of calcium and thus have a lower bone mass.
