When a scientific theory does not contradict other well established scientific hypotheses, it is said to be: O a. empirically adequate O b.internally coherent Oc externally consistent O 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. 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 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? O a. Chronic sleep deprivation causes the brain to become less sensitive to serotonin.

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?
O a. Chronic sleep deprivation causes the brain to become less sensitive to serotonin.
O b. Losing sleep, even for just one night, can have a significant impact on brain function.
OC. Rats are more prone to develop depression than people, especially when they're experimental subjects.
O d. People are more likely to develop depression than rats because they rely more on serotonin.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5117d07f-69cf-4633-b29f-6fe59591d5b0%2F462598e9-b057-43a2-b912-5e72966afea4%2Fli3ur4m_processed.png&w=3840&q=75)
