The hard parts of an insect's body are on the outside and are called an "exoskeleton." The hard parts of a mammal's body are on the inside and are called a "skeleton." Although the two have some similarityes, they are not the same.
No. A snake has a solid skeleton made from bones (in the same way our skeleton is made)
No. Wasps are insects and do not have a backbone.
Essentially the same as that in any other vertebrate - including us. It is the central column of the skeleton, and the conduit for the nerve-bundle that is the spinal cord.
The endoskeleton of vertebrates have at least three main functions. These are: 1. To support the all parts of the body, including limbs, organs, and the head. 2. To protect vital organisms (IE, the skull protects the brain and the ribcage protects the lungs and the heart. 3. Some bones produce red and/or white blood cells. Blood cells, unlike other cells, do not self replicate, so without the marrow in some of our bones, we wouldn't produce new blood cells and we would soon die.

The bat is a mammal and does not have an exoskeleton. It has an internal skeleton the same as other mammals do. You will find exoskeletons on insects.
Both humans and snakes have an exoskeleton made of bone and some cartilage. Both poses a skull, a jaw, vertebrae, and ribs. Some snakes also have a vestigial pelvis.
the same as all butterflies have. besides, since the butterfly is an insect, it would be called an exoskeleton, actually.

Yes. Arthropods have a skeleton on the outside, called an exoskeleton. (By contrast, vertebrates will have an internal skeleton or endoskeleton). The exoskeleton of arthropoda is made of a tough protein called chitin, a long chain polymer comparable to cellulose. It fills the same role as the protein keratin in other animals where it would be found in hair, nails, hooves, claws, beaks, etc. Some arthropods, like crustaceans, further harden their chitin exoskeleton by biomineralization with calcium carbonate. Because it is inflexible, the organism has to periodically shed it (moult) in order to grow, a process called ecdysis.
The exoskeleton on the crayfish is an adaptive advantage because it gives the crayfish support and protection. Unlike humans who have an internal skeleton, the exoskeleton protects the crayfish from its predators. In the case of support, the crayfish's ligament and muscles attach to the exoskeleton, which provides a structure for its internal organs and muscles. The internal skeleton, which provides support, does not provide the same protections as an exoskeleton; however, the exoskeleton also has its disadvantages such as molting. When the crayfish molts, it takes all the calcium out of its previous exoskeleton and holds it in two pockets in its head. The crayfish then flexes its posterior and pushes all the blood toward its anterior, cracking the shell. After climbing out, the crayfish is totally vulnerable to predators because it takes a couple days for the new exoskeleton, which has already developed but is thin and weak, to harden. The calcium stored from the old exoskeleton helps the new one harden, but it still takes a while.
An exterior skeletons (Exoskeleton) method of support is far different than an interior skeletons (Endoskeleton). The major difference is that an exoskeleton has structeres called apodemes, which are chitin structures that serve as attachment sites in the same way that muscles in an endoskeleton attach to the bone.
The same just like with all animals with an internal skeleton: to provide structure and support to the body, as well as protection to the more vulnerable organs in the body.
