Which of these locations is where the impulses to cause a movement, for example away from a stimulus, are initiated? A. skeletal muscle B. spinal cord C. thalamus D. cerebral cortex E. Both B and D are correct.

E. Both B and D are correct.

Explanation:

The motor control consists of different parts of the central nervous system that includes the spinal cord, brainstem, cerebellum, basal ganglia and others. These regions ensures the smooth movement.

The motor cortex is the part of the cerebral cortex it sends the impulse to initiate the movements to the spinal cord the spinal directs the muscles for movement. This way the spinal cord and the cerebral cortex are both responsible for the control and coordination towards the response generated for stimulus.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
