select the two functions of the vertebrae in vertebrates.
contribute a source of calcium for the bones of the rest of the body
provide attachment points for muscles
conduct nerve impulses between the brain and the peripheral nervous system
surround and protect the spinal cord

Explanation:

Vertebrae are bones. Bones in general store calcium, but vertebrae specifically protect the spinal cord (a key nervous - system structure) and provide attachment points for muscles (as part of the skeletal - muscular interaction). Nerve impulse conduction is mainly done by neurons, not vertebrae. While bones in general contribute to the body's calcium pool, this is not a unique or main function emphasized for vertebrae in the context of their role in vertebrates compared to protection and muscle attachment.

Answer:

provide attachment points for muscles, surround and protect the spinal cord
