In an electrical synapse, the action potential traverses the synaptic cleft directly without involving any neurotransmitters. The adjacent neurons are connected to each other by gap junctions. These gap junctions allow movement of other molecules between the two cells including secondary messengers.

Answer:
The alcohol group will have produced the greatest volume of urine
The concentrated salt solution group will have produced the least volume of urine
Explanation:
Alcohol inhibits the antidiuretic hormone. This hormone, also known as vasopressin hormone, is released by changes in serum osmolarity or blood volume. Its function is to keep homeostasis and make kidneys conserve or keep water by concentrating urine and by reducing its volume. By these actions, the antidiuretic hormone stimulates water reabsorption, acording to the organism´s needs. The antidiuretic hormone is very sensitive to the presence of alcohol in the blood. Alcohol inhibits the hormone production and the kidneys eliminate more water than the necessary volume. In other words, alcohol is a diuretic substance that enhances urine production.
Salt ingestion causes an increase in plasmatic osmolarity, stimulates thirst and hence, water ingestion. It also causes an increase in the antidiuretic hormone, which anhances in water reabsorption by the kidneys in its collector tubules. Salt consumption causes a change in osmolarity, which drives to an increase in water reabsorption and an important reduction in urine volume.
