Match the Vitamins given in Column I with the diseases caused by their deficiency as given in Column II.
In this question, we need to match the vitamins with the diseases caused by their deficiency. Let's break it down:
Vitamin K (A) is involved in blood clotting and its deficiency leads to a condition called Haemophilia (S). Hence, A = S.
Vitamin B$_1$ (B) is important for carbohydrate metabolism and its deficiency causes a disease known as Pernicious Anaemia (R). Hence, B = R.
Vitamin B$_2$ (C) plays a role in energy production, and its deficiency leads to a condition called Chelosis (P), which is a disease of the mouth. Hence, C = P.
Vitamin D (D) is essential for bone health, and its deficiency leads to Osteomalacia (Q), a condition of softened bones. Hence, D = Q.
Thus, the correct matching is: A = S, B = R, C = P, D = Q.
Scurvy is caused due to deficiency of:
If the ratio of lengths, radii and Young's Moduli of steel and brass wires in the figure are $ a $, $ b $, and $ c $ respectively, then the corresponding ratio of increase in their lengths would be:
