The purpose of this project is to test how the two skeletal system of the Grizzly bear, Ursus arctos , and Gray wolf, Canis Lupus, are useful for survival, such as their how their speed and strengthdiffers and how they use it. The independent variable used in this report is the type of situations the animal is put into; such as how the skeletal system functions while catching prey or doing something physical and how it helps in the production of blood and endocrine. The dependent variable will be how animal’s skeletal system will react in each of the following scenarios. The Ursus arctos dwells mostly in Alaska or northeastern hemisphere, although it can also be found in the northern hemisphere near Canada and the United States. The Ursus arctos can weigh up to 700 to 1,700 pounds, they are omnivores and can either eat fruits, berries and grasses or salmon, elk and deer. The Ursus arctos can be found in woodlands, forests, alpine meadows and prairies. The Canis Lupus is mostly found in Canada and Alaska and can weigh up to 60 to 145 pounds, they are carnivores and live in packs of as little as two to thirty. Each pack has an alpha male and female who usually lead the wolves in hunt, they prefer to eat Elk, Deer, Bison and Moose: they are the Grizzly Bears biggest competitors. The functional system observed in these animals is the skeletal system. The skeletal system is made up mostly made up of connective tissues, bone, cartilage, tendons, and ligaments. It also stores
