Which one of the following pairs is incorrectly matched?a)Thiamin-Beri...
Explanation:
The incorrectly matched pair among the given options is:
c) Vitamin A - Colour-blindness
Explanation:
Vitamin A is not associated with colour-blindness. Colour-blindness is a genetic disorder that affects the ability to perceive certain colors. It is caused by a deficiency or abnormality in the photopigments in the cones of the retina. Vitamin A, on the other hand, is essential for vision and is necessary for the proper functioning of the retina.
Correctly matched pairs:
a) Thiamin - Beriberi
- Thiamin, also known as vitamin B1, is essential for the metabolism of carbohydrates and plays a key role in nerve function. A deficiency in thiamin can lead to a condition called beriberi, which is characterized by weakness, loss of appetite, and nerve damage.
b) Ascorbic acid - Scurvy
- Ascorbic acid, also known as vitamin C, is necessary for the synthesis of collagen, a protein that helps in the formation of connective tissues. A deficiency in vitamin C can lead to a condition called scurvy, which is characterized by weakness, fatigue, and bleeding gums.
d) Vitamin K - Blood clotting
- Vitamin K is essential for the synthesis of clotting factors in the blood. It plays a crucial role in the process of blood clotting and helps prevent excessive bleeding.
In conclusion, the correct pairings are a) Thiamin - Beriberi, b) Ascorbic acid - Scurvy, and d) Vitamin K - Blood clotting. The incorrect pairing is c) Vitamin A - Colour-blindness.
