C) It requires conscious effort.
D) It bypasses the spinal cord.

Answer 1

A spinal reflex differs from a normal sensory and motor reaction as it does not involve the brain.

Step-by-step explanation:

A spinal reflex differs from a normal sensory and motor reaction in that it does not involve the brain. While normal sensory and motor reactions require information to be processed in the brain, spinal reflexes bypass the brain and involve only the spinal cord. This allows for a quicker response as the signal does not have to travel all the way to the brain and back.
