Final answer:
Geographical location affects the amount of vitamin D the body is able to synthesize.
Step-by-step explanation:
The statement that geographical location affects the amount of vitamin D the body is able to synthesize is True.
Vitamin D is synthesized in the skin when it is exposed to UV radiation. The UV rays from sunlight activate a form of vitamin D3 called cholecalciferol. This reaction occurs more efficiently in areas closer to the equator that receive more direct sunlight.
For example, people living in northern latitudes with limited sunlight exposure may have a higher risk of vitamin D deficiency compared to those living in tropical regions with ample sunlight.
