A few sample questions
1. A deficiency of which vitamin causes scurvy?
Answer: Vitamin C
Scurvy is caused by a severe deficiency of vitamin C (ascorbic acid). It was common among sailors who lacked fresh fruits and vegetables during long voyages.
2. Rickets, a condition that causes soft and weak bones in children, is caused by a lack of which vitamin?
Answer: Vitamin D
Rickets is caused by vitamin D deficiency, which impairs calcium absorption and leads to soft, weak bones. Sunlight exposure helps the body produce vitamin D.
3. Night blindness is an early symptom of deficiency in which vitamin?
Answer: Vitamin A
Vitamin A deficiency causes night blindness because vitamin A is essential for producing rhodopsin, a pigment in the retina needed for low-light vision.
