Answer:
A reflex arc with single synapse (integrating center) is a monosynaptic reflex arc.
Step-by-step explanation:
A reflex arc consists of sensory neurons, motor neurons, integrating center, sensory receptors, and effectors.
A monosynaptic reflex arc is the one that consists of only a single synapse in the central nervous system. This means that the whole monosynaptic reflex arc has only one synapse between single sensory and motor neurons.
