Snakes and lizards flick their tongues in the air to capture scent particles. They don’t smell through their noses like us. In addition,they use their tongues to collect scent particles and then pass them over an organ called a Jacobson’s organ to analyze the air around them. This helps the reptiles hunt for food.

Answer for the Question of the Week

The way potatoes are boiled depends on the heat it receives from water. This depends on the boiling point of water. If the boiling point is lesser, water will vaporize very soon before reaching 100 Celsius. Potatoes don’t receive the required heat for an optimum boil. The boiling point of water decreases when atmospheric pressure is low. And above all, atm pressure reduces with increasing altitude.
