No.
I advise you to look up what saltatory conduction is so you will understand why not rather than coming here to get the answers to your homework.
Saltory conduction only occurs in the myelinated axons.
Saltatory conduction uses myelinated sheaths around the axon to aide in the efficiency that an action potential passes down the nerve's axon by jumping between nodes of ranvier. The word saltatory is taken from the french word "saltare" meaning leap. Saltatory conduction saves time and improves energy efficiency in the nervous system. In some neurological disorders such as Multiple Sclerosis, demyelination of axons occur, resulting in a block of conduction of the action potential.
Saltatory Conduction is a means by which action potentials are transmitted along myelinated nerve fibers. The cytoplasm of an axon is electrically conduction and because myelin inhibits charge leakage through the membrane, depolarization at one node of Ranvier is sufficient to elevate the voltage at a neighboring node to the threshold for action potential initiation. Therefore in myelinated axons, instead of axon propagating as waves but they occur at successive nodes and 'hop' along the axon. This means of travel is much faster than they would otherwise (120 m/sec compared to 35m/sec in unmyelinated nerve fibers). Another advantage of this is that energy is saved as sodium potassium pumps are only required at specific points along the axon. Sean Sinclair
wherever the Schwann cells wrap around the axon, the sodium and potassium ions cannot cross the membrane; the Schwann cells wrap too tightly around the axonal membrane for there to be any extracellular space underneath them. Therefore, the only place that an action potential can occur is at the node of Ranvier-- the space between the Schwann cells. Because of this, the action potential seems to jump from node to node along the axon. "Jumping" is what the word "saltatory" means.
They occur in insulated or myelinated axons.

In invertebrate nerves, axons and dendrites are uncovered, and signal transfer is a fairly slow process. In vertebrates, many axons and dendrites are covered in myelin, a fatty substance which insulates the nerves and speeds up conduction. However, for signal conduction to occur, ions have to be able to move in and out of the nerve along its length to transmit the impulse. Since ions can't diffuse through myelin, they have to go through the nodes of Ranvier. This is called saltatory conduct.
Conduction doesn't occur in fluids. Convection currents are the form in which heat travels in fluids.
It can occur through conduction, convection and radiation.
Because, conduction is the transfer of heat flow fro one object to another. So that means they must touch to make conduction occur.

Synapses occur at synaptic cleft (or also called as "synaptic gap"). The location of "synaptic cleft" depends on the types of synapses:axo-dendritic synapse : between axons and dendritesaxo-somatic synapse : between axons and cell bodiesaxo-axonic synapse : between axons and axonsdendro-denritic syanpse : between dendrites and dendrites
