Document Summary

If a camel doesn"t eat the hump ops over. The hump can weigh up to 80 lbs. It allows the animal to survive a long time (up to 2 weeks) with limited food. Camels do not store water, they store the fat tristearin (c57h110o6) This fat is also a source of water when it is metabolized. Allowing camels to undergo long periods without drinking water. 2c57h110o6 +163o2 114 co2 + 110 h2o (equation for the breakdown of fat to be used as water) If you break bonds in the large molecule, there is a lot of potential energy reduced. Camels do not generally use this fat for water production. Camels can endure long periods without water because: They have an extreme tolerance to water loss up to 30 - 40% of their body weight. They can minimize water losses (i. e. condensing water in the nostrils) Migrating geese have distinct and challenging routes. As winter approaches they migrate to southern states.
