The functions of the humps in camel is to __:
1. Store water
2. Store fat
3. Insulation of heat
Choose the correct option from the codes given below:

Answer: [C] Only 2 & 3

Camels do not store water in their humps as is commonly believed. The humps are actually a reservoir of fatty tissue. Concentrating body fat in their humps minimizes heat-trapping insulation throughout the rest of  their body, which may be an adaptation to  living in hot climates. When this tissue is metabolized, it acts as a source of energy, and yields more than 1 g of water for each 1 g of fat converted through reaction with oxygen from air. This process of fat metabolization generates a net loss of water through respiration for the oxygen required to convert the fat.
