- You are designing an experiment to determine if you can make desert kangaroo rats active at noon. At noon the ground and air are warmer than the internal temperature of the rats. You decide to provide the kangaroo rats with enough water to ensure they can maintain body temperature homeostasis. Based on a simplified model, you determine that at noon, kangaroo rats: - Absorb 8 watts of radiation - Generate 1 watt of metabolic heat - Re-radiate 1 watt - Exchange a total of 2 watts with the surrounding desert ground and air via conduction - Exchange 4 watts through convective processes The kangaroo rat is not in energy balance. Since kangaroo rats lose 1 watt through latent heat (i.e. evaporative cooling) with each 2 ml of water consumed, how much water would you need to provide the kangaroo rat so that it can reach homeostasis? 04 8.
