Question

what disadvantage would you face if your backbone is made up of just one long bone?

Answer 1

Normally your back bone or spine is made of many segments (divided into three groups) which allow you to bend and fully articulate your body. This helps you to comfortably move around, run, sleep, walk etc.. If your backbone is just one long bone, oh won't be able to perform any such activities and would cause back pain termporarily or permanently.

Hope it helps :) !!!

Answer 2

It would be difficult for us to eat, sleep, play.
