Question

question 29
a lack of which of the following major minerals can lead to slow growth and weak and brittle bones?
potassium
magnesium
sodium
calcium

Explanation:

Calcium is a crucial mineral for bone health. Bones are mainly composed of calcium. A lack of calcium can lead to slow growth in children (as bones need calcium for proper development) and in both children and adults, it can result in weak and brittle bones (osteoporosis in adults is often associated with calcium deficiency over time). Potassium is important for nerve function and fluid balance, magnesium for muscle and nerve function and energy production, sodium for fluid balance and nerve impulse transmission. None of these have the direct role in bone structure and growth like calcium does.

Answer:

Calcium
