Sensory neuron, interneuron, motor neuron, effector

Motor neuron, interneuron, sensory neuron, effector

Sensory neuron, motor neuron, interneuron, receptor

Motor neuron, interneuron, sensory neuron, receptor

Answer 1

I think it would be 3. Hope this helps

Answer 2

Answer:

A.

Explanation:

As soon as the girl steps on the shell, the first thing that happens is that the sensory neuron, which in this case is located on the skin, receives the information and transfer it to the inter-neuron or the association neuron which is located between the motor and the sensory neuron. From there, the motor neuron relays the information to the effector e.g a muscle that responds to the stimulus by removing the foot immediately.
