Answer to Question 1

Ans: B
The synaptic cleft, a junction between one nerve and another, is the space where the electrical intracellular signal becomes a chemical intracellular signal. The soma is the neuron's cell body. A terminal is the end of an axon. A receptor site is the area of the postsynaptic membrane that accepts the released neurotransmitter.

Answer to Question 2

Ans: D
Schizophrenia is associated with abnormally high activity of dopamine, not serotonin. Therefore, the students would need additional review. Whereas depression and insomnia have been associated with decreased levels of 5-HT, mania has been associated with increased 5-HT. Some of the most well-known antidepressant medications, such as fluoxetine and sertraline, function by increasing serotonin concentrations within certain areas of the central nervous system..

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.

The average older adult in the United States takes five prescription drugs per day. Half of these drugs contain a sedative. Alcohol should therefore be avoided by most senior citizens because of the dangerous interactions between alcohol and sedatives.
