Question
4. Who would you expect to be most at risk for developing the bone disease rickets?
Children born to mothers with dark skin, living far from the equator
b. Adults with dark skin who live close to the equator
c. Children born to mothers with light skin, living close to the equator
d. Adults with light skin who live close to the equator
e. Anyone who eats a diet that includes a lot of fish
5. Explain the reasoning or evidence you used to answer Question 4.
Answer
The answer to Question 4 is A: Children born to mothers with dark skin, living far from the equator. This is because rickets is caused by a lack of Vitamin D, which is produced in the skin when exposed to sunlight. Darker skin absorbs less sunlight, so people with dark skin living far from the equator are more likely to be deficient in Vitamin D and therefore more at risk for developing rickets.
