Question 2 Why do small Arctic mammals enter hibernation whereas larger mammals stay active during the winter months? smaller mammals have a low metabolic rate so hibernate to maintain this low need for energy and fuel. smaller mammals lose heat faster due to their small body size and high surface area: volume ratio. smaller mammals consume less oxygen per kilogram than a larger mammal and hibernate in order to maintain this low consumption rate. O smaller mammals hibernate in order to increase metabolic demand for the winter months.

Question 3 Like the mice in our experimentyour body relies on metabolic means and/or shivering to maintain body temperature. Why does the body use shivering as a secondary means as opposed to the primary means of maintaining temperature? 1. Shivering consumes a lot of carbon dioxide and this throws off the pH of our blood. 2. Shivering requires a greater use of oxygen and is, therefore, more energetically costly. 3. Shivering requires less oxygen use and more energy.
