No, rats have more bone than cartilage, same as most mammals. However, their skeleton has more flexibility at the joints, particularly the pectoral girdle and rib cage, which allows them to bend and squeeze into spaces that do not look big enough for a rat.
the shark has about 85% of the body is cartilage because with out it they can not move as fast or as agile as they are with it
Half And Half Really, The Tail Is Where The Spine Ends So That's Why You Have To Be Careful With It. :)
I think there are more rats in the world than humans.
Sharks are a type of cartilaginous fish, that is their skeleton is made of cartilage rather than bone. They belong to the vertebrate subphylum of chondrichthyes.
The skeleton of jawless fish, such as lampreys and hagfish, is primarily made of cartilage rather than bone. Cartilage is a flexible and lightweight tissue that provides structure and support to these fish without the need for heavy bones.
Cartilage is a far more primitive tissue than bone
Because bone is much harder than cartilage
The opposite of Cartilage Are Ligaments because the cartilage is more flexible than bone.
Bone is far more vascular than cartilage, which means the bone receives nutrients/oxygen/other good stuff more and easier than cartilage. Cartilage has almost no blood supply, which makes healing difficult. Hope that helps..
No, it is not. Bone is strong but it doesn't bend easily. Cartilage is more flexible.
Teeth are teeth, neither cartilage or bone. But more similar to bone than cartilage.
Cartilage
cartilage is more flexible than bone making the shark more hydrodynamic.
Not really. The nails are more of a compact layered skin structure. Cartilage is more for cushioning and lubrication between bones. Some areas do have a rigid structure of cartilage, but it's softer than nail tissue.
It is known as cartilage.
Cartilage is a tough, flexible connective tissue that is softer than bone. It provides structure and support to various parts of the body, such as the joints, ears, and nose. Cartilage also helps cushion and protect bones from rubbing against each other.
how the canaliculi allow bone to heal more efficiently than cartilage.
