Answer 1

Answer:

a.The spine (or backbone) runs from the base of the skull to the pelvis. It serves as a pillar to support the body's weight and to protect the spinal cord. There are three natural curves in the spine that give it an "S" shape when viewed from the side.

b.Human backbone provides support to our body and helps in the movement. The structural composition of back bone allows us to bend, crouch, stand and lie down on the ground. ... One single bone means no flexibility in the structure of a bone.
