Quiz Please Note:  It is recommended that you save your response as you complete each question. Scientific Study New research has found that young adults who napped for 90 minutes after lunch raised their learning power,  their  memory  apparently primed to absorb new facts.  The findings were published in the American  Association for the Advancement of Science Journal. “You need to sleep before learning, to prepare your brain, like a dry sponge, to absorb new information,” said  the lead investigator.  This is probably due to the adaptive advantage of sleep throughout many evolutionary  branches, since similar results have been seen even in animals as distantly related to humans as birds” The study recruited 9 healthy young adults and divided them into two groups. All 9 were asked to learn 100  names and faces at noon, and then to learn a different set of names and faces at 6 p.m. But 5 of the  volunteers who napped for 90 minutes between the two learning sessions improved their scores by 10 percent  on average after sleeping; the scores of those who didn’t nap actually dropped by 10 percent.   Answer questions 1-3 from the above abstract Question 1  (2 points)   From the study performed, the authors can conclude: Question 1 options: 1) sleep is important for memory tasks in young healthy adults 2) sleep is important for most brain functions in young healthy adults 3) sleep is important for memory tasks in people and birds 4) sleep is important for memory tasks in all people Save Question 2  (2 points)   The conclusions (statement) presented by the lead investigator provide: Question 2 options: 1) ultimate proof that napping is always important 2) a proximate explanation for sleep 3) ultimate proof that napping is not important 4) an ultimate explanation for sleep Save Question 3  (2 points)   A ccording to class discussion, the article would be good science for all of the following reasons except: Question 3 options: 1) the study contained proper controls 2) the study was published in a reputable journal 3) the study was done on a large sample 4) the study involved objective measurements

Save Question 4  (2 points)   DNA sequences of the collagen gene were compared between humans and several other species, dog, fish,  turtle and frog. Which of them is most likely to be from the dog?   ACT CAT GAG (human) Question 4 options: 1) AAT TAT GAG 2) ACT TAT GGG 3) ACT TAT GAG 4) ACT TTT GAG Save Question 5  (2 points)   A belief: Question 5 options: 1) cannot be affected by repetition 2) cannot be affected by emotional input 3) is a good way to support scientific theories
