QUESTION 55
When a scientific theory does not contradict other well established scientific hypotheses, it is said to be:
а.
empirically adequate
b. internally coherent
OC. externally consistent
d. fruitful
QUESTION 56
Consider the following scientific experiment:
"Studies suggest sleeping too little for too long can change the brain. In a study of rats, Meerlo examined serotonin
-a brain chemical thought to be important in sleep, depression and many brain functions. The researchers didn't
find any changes in the rats brains after a single night of sleep loss, but after a week of getting shortchanged, the
rats' brains became less sensitive to serotonin. Such changes could make rats, and people, more prone to
developing depression, Meerlo says" (p. 32). [Science News, 10/24/09.]
What causal hypothesis was Meerlo trying to test in his study?
Chronic sleep deprivation causes the brain to become less sensitive to serotonin.
a.
D. Losing sleep, even for just one night, can have a significant impact on brain function.
O Rats are more prone to develop depression than people, especially when they're experimental subjects.
d. People are more likely to develop depression than rats because they rely more on serotonin.
