You've accurately matched the biomolecules with their corresponding functions or diseases. Here's a breakdown:
List I - Biomolecules and List II - Functions/Diseases:
- (A) Vitamin A: (II) Xerophthalmia
- Vitamin A is crucial for vision, particularly in low light.
- Deficiency leads to Xerophthalmia, characterized by dry eyes and night blindness.
- (B) Thiamine (Vitamin B1): (III) Beri-Beri
- Thiamine is essential for carbohydrate metabolism and nerve function.
- Deficiency causes Beri-Beri, affecting the nervous and cardiovascular systems.
- (C) Glucocorticoids: (IV) Addison's disease
- Glucocorticoids (like cortisol) are hormones produced by the adrenal glands.
- Addison's disease occurs when the adrenal glands don't produce enough glucocorticoids and mineralocorticoids.
- (D) Estradiol: (I) Menstrual cycle
- Estradiol is a form of estrogen, a female sex hormone.
- It plays a vital role in the regulation of the menstrual cycle.
Therefore, the correct matching is:
- A - II
- B - III
- C - IV
- D - I
This is a correct and well-explained matching.
