Answer 2

In some desserts, the air temperature can vary over 60 to 70 degrees in a single day. Being Endothermic is the property which allows humans to persist in an environment that has such drastic changes in temperature,

Option (B)

Explanation:

• Endotherm means warm-blooded animals, likewise Humans are warm-blooded. The metabolism helps them to regulate the internal body temperature and cope up with the changing environmental temperatures.
• When the heat lowers down, the metabolism uses up internal energy to make up with the temperature fall and when the temperature increases the metabolism again works to handle the temperature increase up to some extent. This process requires the continuous supply of fuel i.e. food.
