Question

Which one of the following is not associated with nitrate exposure in humans?

a. goiter.
b. blue baby syndrome.
c. risk of developing insulin-dependent diabetes.
d. brittle bones.

Answer 1

The correct answer is d. brittle bones.

Step-by-step explanation:

Brittle bone disease is a genetic disorder that causes the bone to become fragile that easily breaks. It is also known as osteogenesis imperfecta which means imperfect bones.

In this disease, a gene that makes type 1 collagen becomes defected. Type 1 collagen is an important protein that is required to make bones. This defective gene mainly comes from parents. So brittle bone disease is not associated with nitrate exposure in humans while goiter, blue baby syndrome, and risk of developing insulin-dependent diabetes are associated.
