2. True (1 point). Research has found that people with low levels of vitamin D in the blood were twice as likely to suffer premature death than those with an adequate level.
3. D. (3 points). Down’s Syndrome is NOT caused by a vitamin D deficiency, though children with Down’s could have a D deficit. A, B, and C are all true:A. Studies show that time spent in the sun each day can cut your risk for breast cancer in half.
   B. Research also indicates a relationship between multiple sclerosis and vitamin D deficiency.
   C. Pregnant women with vitamin D deficiency are twice as likely to have children with language difficulties.
4. F. All of the above (2 points). It’s hard to think of an aspect of your body’s functioning that is NOT affected by vitamin D! Some people are surprised to learn that calcium does little to help your bones or teeth if you aren’t getting Vitamin D for teeth strengthening. Vitamin D starts the development of calcitriol, which is a hormone regulating calcium levels in the body. It thus triggers the development of bones and teeth. Calcitriol also allows the intestines to absorb calcium.
5. True. (1 point). Melanin is what makes skin dark but it also protects you from the sun’s rays. That’s why it takes more sunlight to get enough vitamin D when your skin contains more melanin.
