Which of the following describes the pathway that nerve impulses travel while throwing a baseball? a. motor neuron → spinal cord → sensory neuron → muscles b. sensory neuron → spinal cord → motor neuron → muscles c. motor neuron → brain → sensory neuron → muscles d. sensory neuron → brain → motor neuron → muscles

D. sensory neuron → brain → motor neuron → muscles

Explanation:

First, your hand feels the ball when touching it, and using sensory neurons, an impulse is sent to the brain. The brain then processes the information obtained from the sensory neuron and sends another signal trough the motor neuron carrying the message to the muscle.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
