 **Compare the bones of the humerus and carpals in birds and humans.** When it come to the humerus in humans and birds seem to be the same and the same can be said the carpals. The only differences that can be found between them is the ways in which they use these bones. Because birds and humans evolved from a common ansestor then it is uses that are not a common trait. Birds use there wings to fly and humans use there arms for many things like throwing a baseball. @http://askabiologist.asu.edu/human-bird-and-bat-bone-comparison **How many bones per phalanges in humans? ** There are 20 bones because phalanges are the bones between the finger and toes. We have 10 fingers 10 toes which equals 20. **How many metacarpals? ** Humans have 5 metacarpals in each hand totallying 10. //1. describe the internal structure of the bird and human bones you see above.// The internal stucture of the human bone is more intercate then that of the birds. It looks like if someone put in more time to make it so that it would last longer. //2. Why do you suppose bird bones are so hollow?// I believe that the reason birds bones are hollow because they grow at a faster rate then humans do. When it comes to the structure of bones, it all really depends on how fast or slow they grow. A more well developed structure, the slower bones grew and a bone that is simple tends to be due to a fast growing bone. Bones consist of minerals, protiens, blood vessels, nerves, cells that are both hard and soft. Based on the growth rate, this will determine how structred a bone will be. In general, the more organized a bone's microscopic structure is, the slower it grows. Sometimes, bones stop growing when it gets cold outside or resources are not readily available Is measured in the same way that the growth of a tree would be. Longevity through the application of rates obtained from bone vascular and fiber composition. One of the strategies that is used is to measure bones in the later year of life which are the years that most living creatures obtain their mass.
