Bio301D Exam 1 27 Sept 06 Name (required) _____________ 1. (5 pts) The following statements pertain to the first-day survey and the discussion of it in the following lectures. Which statements are true? (multiple True/False = MTF) (A) Highly varied responses were observed for some statements. The discussion that followed suggested that most of the variation in responses was due to students having different levels of direct knowledge of the relevant evidence. (B) Comparing classes from different years, responses to the same statement are usually similar. (C) It was suggested that emotional factors were important in many of the responses. (D) More students considered it “definitely” or “probably” true that governments had concealed evidence that aliens have landed on earth than considered it definitely or probably true that aliens have even landed. (E) The purpose of this survey was to assess your baseline knowledge of basic biological facts. Scientific Method 2). (4 pts) The figure below shows the steps of the scientific method, labeled (i)-(viii). Which of the following options are true? You are assumed to know the identity of these steps for this question. In two cases, you are asked to relate the elements of this figure to demonstrations done in class. (MTF) (A) “Data” are part or all of (iv) and (viii). (B) What we refer to as the scientific method includes all steps but (i) (C) Omission of (vii) still enables progress in the long term, if not the short term. (D) For the in-class demonstration using the “Wheel of Fortune” game, your guesses at letters in the blanks were examples of (ii). 3. (5 pts).

Bio301D Exam 1 27 Sept 06 Name _____________ 4. (5 pts) David is writing a computer program to determine all whole numbers between one and a billion (10 9 ), which when multiplied by 3, give a palindrome (a palindrome reads the same way forward as backward). The first 10 of these numbers were given to him by someone else, but there are possibly hundreds or thousands of numbers satisfying this criterion. He starts out by writing a simple computer program. It fails to generate even his list of 10, so he looks closely at the program and discovers that the program approximates numbers rather than treating them as exact values. He fixes this problem. Now his program correctly provides his list of the first ten palindromes plus others; these others are correct solutions to the problem. But the program has another difficulty: the program stops considering numbers at 10 8 , so David still does not know the palindromes between 10 8 and 10 9 . After calling a friend for help, neither of them is able to solve the problem. The program remains unfixed, and David has an incomplete list of solutions to his problem.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
