chemically gated channels
The transport mechanism for a neurotransmitter across the synaptic cleft is called exocytosis. During exocytosis, neurotransmitter-filled vesicles fuse with the presynaptic membrane, releasing the neurotransmitter into the synaptic cleft where it can then bind to receptors on the postsynaptic membrane.

Vesicles in an axon move towards the membrane due to the activity of molecular motors such as kinesin and dynein. These motors use ATP to move along microtubules in the cytoskeleton, carrying vesicles to their destination at the axon terminal. This movement is essential for the release of neurotransmitters during synaptic transmission.
The K+ leak channel is the most important. It opens at around -70mV.
I believe varicosity in the context of your question refers to the enlarged and tortuous vein, artery, or lymphatic vessel in the area of the synapse. Therefore in the aplysia synaptic junctions between the sensory and motor neurons experience long term facilition in response to 5-HT and long term depression in response to RMRFamide. Research has shown macromolecules synthesis is needed for expression of the long lasting structural changes in the sensory cells and that this synthesis is porportional with long term functional modulation of sensorimotor synapses.
Chemically Gated Channels.
Synaptic vesicles are found in the axon terminals of nerve cells.
Cardiorespiratory endurance
1. Nerve impulse reaches synaptic terminal. 2. Synaptic vesicles move to and merge with the presynaptic cell membrane of the motor neuron. 3. Acetylcholine is released into and diffuses across the synaptic cleft. 4. Acetylcholine binds to receptors on the postsynaptic cell membrane of the muscle fiber.

Perhaps "Do not MOVE around the room during an activity".
All you can really know for certain from a dream is that somewhere you thought of it, or had a memory of it. A dream is simply your brain trying to make sense of random synaptic activity during REM sleep. Your waking thoughts and memories are often shuffled around during this process which is what makes for such buzzer happenings.
No, RNA polymerase does not have exonuclease activity during transcription.
