Ques. 1AIPMT 2001
Which set is similar?
- Vitamin B7 – Niacin
- Sebum – Sweat
- Corpus luteum – Graafian follicles
- Bundle of His – Pacemaker
Answer
(3) Corpus luteum – Graafian follicles
Solution
As per NCERT, after ovulation the ruptured Graafian follicle transforms into the corpus luteum, which secretes progesterone.
∵ Vitamin B7 is biotin (niacin is vitamin B3), sebum and sweat are secretions of different skin glands, and the pacemaker (SA node) and the bundle of His are different parts of the conducting system of the heart,
∴ corpus luteum – Graafian follicles is the similar (related) set.
Answer: (3)
