Answer:
A neuromuscular junction is a junction between a <em>nerve fiber</em> and a <em>muscle cell.</em>
Explanation:
<em>A neuromuscular junction (or myoneural junction) is a site of chemical communication between a nerve fiber and a muscle cell, is analogous to the synapse between two neurons. </em>
A motor neuron is able to transmit a signal to the muscle fiber, causing muscle contraction upon stimulation by a nerve impulse, the terminal releases the chemical neurotransmitter acetylcholine from synaptic vesicles binding to the receptors, the channels open, and sodium ions flow into the endplate, this initiates the end-plate potential, the electrical event that leads to contraction of the muscle fiber.

The answer to this question would be nine quadrants
Auscultating is an examination where you put stethoscope into the patient chest and try to hear their breathing/heart sound. The lung is a big organ but contains multiple lobes, so when there is an abnormality in a part the sound might not be heard in the other lobes.
It is important to auscultate the lung into at least 9 quadrants so you won't miss it.
E. coli bacteria would not have a well defined nucleus, because bacteria are prokaryotic cells.
The onion cell and the human brain cell would be eukaryotic cells, which do have nuclei.
