CNS/Endocrine Practice FRQ
Your name:
Xander was walking home from work, listening to music on airpods, and generally feeling relaxed. He was
almost home when, suddenly, he spotted a ferocious looking dog snarling and barking, and it began to run
towards him. Even though Xander had never seen a dog like this before, almost instantly, he felt a jolt
of shock
his heart began pumping hard, he began sweating, and every fiber in his being seemed to scream 'RUN!" He
bolted inside, seemingly quicker than he has ever run, and slammed the door just in time. Relieved, but still
worked up, it took Xander a few minutes to feel normal again.
a) Explain how Xander's nervous and endocrine systems functioned in this scenario, using these terms:
• Sympathetic nervous system
• Endocrine system
Adrenal glands
Central nervous system
Somatic nervous system
Parasympathetic nervous system
.
b) Explain how this behavior reflects a hereditary trait's selection through adaptive value.

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.18. what can you conclude? 2(0.18) = 0.36 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 18% of the time, so the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 82% of the time, so the test is not statistically significant. 0.18 > 0.05; the test is statistically significant. p = 1 - 0.18 = 0.82 > 0.05; the test is statistically significant.
