Question

what would happen if our backbone is made up of a single bone instead of 33 small vertebrae​

Answer 1

Answer:

It would not be flexible like it's is right now we would not be able to bend or do other kind of activities how we are doing a single long bone cannot bend down or back wards so we would be sitting straight if we would have a long straight bone

Answer 2

Human backbone provides support to our body and helps in the movement. ... If back bone is made up of one long bone then we would never be able to sit, crouch or lie. One single bone means no flexibility in the structure of a bone
