Answer 2

The correct sequence of a reflex arc is: receptor, afferent neuron, interneuron, efferent neuron, effector.

Step-by-step explanation:

The correct sequence of parts in a reflex arc is:

Receptor, Afferent Neuron, Interneuron, Efferent Neuron, Effector.

Here's a step-by-step explanation:

1. The receptor detects a stimulus or a change in the environment, such as touching a hot object.

2. The afferent neuron carries the sensory information from the receptor to the central nervous system (CNS), in this case, the spinal cord.

3. In the spinal cord, the message is passed to an interneuron that connects the sensory neuron to the efferent neuron.

4. The efferent neuron carries the motor information from the CNS to the effector, which is the muscle that will produce a response, for example, pulling your hand back from the hot object.

So, the correct sequence is: receptor, afferent neuron, interneuron, efferent neuron, effector.
