Which one of the following pairs is not correctly matched:
- Vitamin C–Scurvy
Vitamin B2–Pellagra
Vitamin B12–Pernicious anaemia
Vitamin B6–Beri-beri
The Correct Option is D
Solution and Explanation
Beri-Beri is caused by a deficiency of vitamin B1 (thiamine), not vitamin B6 (pyridoxine).
So, the correct option is (D): Vitamin B6–Beri-beri

- Ribose and 2-deoxyribose have an important role in biology. Among the most important derivatives are those with phosphate groups attached at the 5 position. Mono-, di- and tri-phosphate forms are important, as well as 3-5 cyclic monophosphates. Purines and pyrimidines form an important class of compounds with ribose and deoxyribose. When these purine and pyrimidine derivatives are coupled to a ribose sugar, they are called nucleosides.

- Consider the diameter of a spherical object being measured with the help of a Vernier Callipers. Suppose its 10 Vernier Scale Divisions (V.S.D.) are equal to its 9 Main Scale Divisions (M.S.D.). The least count in the M.S. is 0.1 cm and the zero of V.S. is at -0.1 cm when the jaws of Vernier callipers are closed. If the main scale reading for the diameter is \(M = 5\) cm and the number of coinciding vernier division is 8, the measured diameter after zero error correction, is:

Vitamins
Vitamins are natural and essential nutrients. In the growth and development of the human body it plays an important role. For proper growth, strong bones and good development needs the right quantity of vitamins in our body. These vitamins are organic substances that work in groups for the normal and smooth functioning of our body cells.
Types of Vitamins:
There are two main types of vitamins.
Fat-Soluble Vitamins-
Fat-soluble vitamins are stored in the fat cells. These vitamins require fat in order to be absorbed. Vitamin A, D, E and K are fat-soluble vitamins.
Water-Soluble Vitamins-
Water-soluble vitamins are not stored in our body because its excess gets excrete through the urine. Therefore, these vitamins need to be replenished constantly. Vitamin B and C are water-soluble vitamins.
