Individuals who live in locations with limited exposure to sunlight can have abnormal bone development due to an inability to absorb calcium and phosphate ions from the small intestine. Why does a limited exposure to sunlight cause abnormal bone development?A. Cholecalciferol, or vitamin D3, is necessary for the normal absorption of calcium and phosphate ions. Vitamin D3 is made by cells in the epidermis due to exposure to sunlight. Without enough exposure to sunlight, the body won't produce enough vitamin D3B. People are more depressed in areas with limited sunlight, and depression can cause abnormal development of bones. C. People exercise less in areas where there is limited sunlight. This lack of exercise can cause abnormal development of bones. D. People sleep more in areas of limited sunlight.
