Answer 2

Explanation:

1. (Retinol Deficiency)

Vitamin A deficiency can result from inadequate intake, fat malabsorption, or liver disorders. Deficiency impairs immunity and hematopoiesis and causes rashes and typical ocular effects (eg, xerophthalmia, night blindness).

2. Among the B vitamins, one of the earliest deficiency syndromes to be discovered was beriberi, a deficiency of vitamin B1 (thiamine). The symptoms of beriberi are weakness and numbness in the feet and legs, swelling, difficulty breathing, and heart failure.

3. In developed countries, vitamin C deficiency can occur as part of general undernutrition, but severe deficiency (causing scurvy) is uncommon. Symptoms include fatigue, depression, and connective tissue defects (eg, gingivitis, petechiae, rash, internal bleeding, impaired wound healing).

4. Rickets is a rare disease that causes the bones to become soft and bend. African American infants and children are at higher risk of getting rickets. In adults, severe vitamin D deficiency leads to osteomalacia. Osteomalacia causes weak bones, bone pain, and muscle weakness.
