Answer 2

We are able to stand upright because (2) our backbone holds the body verticallyup.

Explanation:

• Our skeleton is made up of two legs with locking knee joints and an upright spine that acts as a support column, holding the weight of the head, neck and trunk and allowing us to stay upright.
• Balance on the other hand, is determined by a lot more than your bones. To help you stand in line at the store, your ears, eyes, brain, spinal cord, heart and muscles all work together.
• The spine often known as the backbone, is the major support structure of your body. It joins the various sections of your musculoskeletal system together. Our spine assists in sitting, standing, walking, twisting and bending.
