Document Summary
Lecture 8: skunk cabbage has an unusual adaption for the cold - it increases its metabolisms and generates heats, thus melting the snow around it. #1: the boreal forest is dominated by spindly and spire shaped trees. They want to lose more body heat so they send the heat to their tails. By diverting more blood through their tails, 90% more heat is lost than when the rete mirabile is in operation: honeybees are social insects that work together to air cool their hive. They use their wings to fan inside their hives to get the heat out: panting is a form of evaporative cooling (i. e. foxes, birds, bees), allowing more moisture to pass over and more body heat to be released. #2: the third challenge is nutrition, majority of plants can make their own food through photosynthesis, but they.
