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.
