Which part of a reflex arc would connect a sensory neuron from the face and neck to a motor neuron in a lower section of the spinal cord? ventral root interneuron effector dorsal root

Interneuron  / SO it will be B.

no pun intended

Interneuron

Explanation:

In a reflex arch, a receptor detects a stimulus such as a receptor in the tip of a fingers have receptors. As a result, impulses generated due to the stimulus are travelled through the sensory neurons to the interneuron or relay neurons present in the spinal cord. The relay neurons connects sensory neuron to the motor neurons. the motor neurons carry impulses to the effectors. The effector produces a response such as move away  from stimulus.

the answer is b: 1.4 km/hr

answer; three;
