Answer (1)
This question is about matching different nutrients and their roles in the human body. Let's look at each item and find its correct pair:
Water - (iv) Keeps the body cool
Water helps regulate body temperature through the process of sweating and evaporation. It's essential for hydration and maintaining bodily functions.
Carbohydrate - (i) Source of energy
Carbohydrates are the body's main source of energy. They are broken down into glucose, which is used by cells to carry out various functions.
Vitamin K - (v) Clotting of blood
