Document Summary

According to myth, camels carry water in their humps. In actuality, the camel hump consists of fat, which can weigh up to 80 lbs. Has evolved to be there due to the camel"s lifestyle. The amount of fat is meant to be a source of energy (atp), as opposed to a source of water. This is also a source of water when it is metabolized, allowing for camels to undergo long periods without drinking. This process is aerobic, in that it requires oxygen to be the nal electron acceptor. Camels" physiology allows them to endure long periods without water. They have large nostrils that encourage condensation within their nasal cavity, and the water droplets get absorbed. They have an extreme tolerance to water loss (up to 30-40% of their body weight) Their faces are extremely dry because their intestines extract a lot of water. Geese have the ability to y, and also migrate.
