Document Summary

Applied lecture 1: amazing energy reserves in animals. The camel hump consists of a giant mound of fat. The hump can weigh up to 80 lbs. This allows camels to survive up to 2 weeks with limited food. Camels do not store water, instead they store the fat known as tristearin c57h110o6. This fat is also a source of water when metabolized, thus allowing for camels to undergo long periods without drinking as well. However, camels do not generally use this fat for water production. Camels can endure long periods without water for two reasons: 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) In the spring and summer, the geese eat leaves, grass, owers, stems, roots, seeds, ect. They can often eat for up to 12 hours a day, and feed even more intensively right before they y (before and after winter)
