A skeleton is a system of bones that force you to move our body
Over 650 skeletal muscles.
It is called a tree and may be made from wood, fibre glass or a composite material.
1. Protection 2. Blood cell formation 3. Storage I dont no the last one but this is for 6th grade so beat it
There's 300 or so at birth, but some of these fuse during childhood. A full adult human skeleton has 206 bones.
Not known. In Stormbreaker Sarah Bolger played Sabina. She could come back or the directors will want someone younger than her.
This is a really hard question to answer. Remember - sharks are a big family of organisms and vary in size to animals the size of whales to animals you could hold in your hand. And the number of cells will thus vary accordingly. Secondly, it's simply very hard to count the number of tiny cells in a large multicellular animal. Different, tissues have different sizes of cells and it would take a lot of painstaking work to figure a precise answer out. Now, it's been estimated that humans have approximately 100 trillion cells. I'm not sure where this number came from but it's been in a few of my text books. I don't think it's a number people give to much effort into determining precisely. But this estimate should give you a sense of the order of magnitude, rather than be considered any where near a precise value. I would assume that a shark about the size of a human would have roughly the same number of cells, although it is possible that human and shark cells may vary significantly enough in size that this estimate may not be useful.
