Why would Have happened if our back bone was made up of a single homestead of number of smaller bones

Answer 1

Heya!

If our back bone wasn't made up of a number of smaller bones an instead, was made up of a single bone, we would not be able to bend down or fold our backs.

Hope this helps!

The structural composition of back bone allows us to bend, crouch, stand and lie down on the ground. The vertebral units promote this 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.
