    • A. 

      Cellular specialization

    • B. 

      Metabolism

    • C.

  • 9. 
    A student wanted to study the effect of nitrogen fertilizer on plant growth, so she took two similar plants and set them on a window sill for a two-week observation period.  She watered each plant the same amount, but she gave one a small dose of fertilizer with each watering.  She collected data by counting the total number of new leaves on each plant and also measured the height of each plant in centimeters.  Which of the following is a significant flaw in this experimental set-up?
    • A. 

      The is no variable factor

    • B. 

      There is no control

    • C. 

      There is no repetition

    • D. 

      Measurable results cannot be expected

  • 10. 
    Students placed five pillbugs on the dry side of a choice chamber and five pillbugs on the wet side.  They collected data as to the number on each side every 30 seconds for 10 minutes.  After 6 minutes, eight or nine pillbugs were continually on the wet side of the chamber, and several were under the filter paper.  Which of the following is NOT a reasonable conclusion for these results?
    • A. 

      It takes the pillbugs several minutes to explore their surroundings and select a preferred habitat.

    • B. 

      Pillbugs prefer a moist environment

    • C. 

      Pillbugs prefer a dark environment

    • D. 

      Pillbugs may find chemicals in dry filter paper irritating.

    • E. 

      Pillbugs demonstrate no significant habitat preference

  • 11. 
    If a student wanted to determine whether pillbugs prefer a moist or dry environment, what would be the best way to analyze data from the experiment?  (Hint:  We might not have used the best method in class)
    • A. 

      Total the number of pillbugs on the dry side throughout the experiment and compare this with the number on the wet side throughout the experiment

    • B. 

      After waiting 5 minutes for the pillbugs to acclimate, count the number of pillbugs on the dry side every 30 seconds for 5 minutes. Total and average the results, and compare this with the number of pillbugs on the wet side during this same time interval

    • C. 

      Compare the number of pillbugs on the dry side at the end of 10 minutes with the number of pillbugs on the wet side at the end of 10 minutes

    • D. 

      Divide the number of pillbugs on the dry side throughout the experiment by the number on the wet side throughout the experiment.

  • 12. 
    Which of the following hypotheses is stated best?
    • A. 

      If pillbugs are allowed free movement, then more will be found in a moist environment than in a dry environment

    • B. 

      If pillbugs like a moist environment, then they will move to the wet side of a choice chamber.

    • C. 

      If an experiment with pillbugs is run for 10 minutes, then more pillbugs will be found in the most favorable environment

    • D. 

      Pillbugs are found in moist habitats, so I predict that more will be found where it is wet.

    An investigation was set up to determine the effectiveness of a particular fertilizer on the  growth of bean plants. In the investigation, each of the 10 bean plants in group A was watered  with 50 milliliters of a solution of distilled water and fertilizer, while each of the 10 bean plants  in group B was watered with 50 milliliters of distilled water only. Both groups of plants were  watered every other day for 1 month and grown under identical environmental conditions. The  control for this investigation was...
    • A. 

      Group A only

    • B. 

      Group B only

    • C. 

      Group A and B

    • D. 

      Neither group A or B

    Data Table Temperature (C) Strain A # of colonies Strain B # of colonies 25 10 11 28 10 7 31 11 3 34 12 0       A student performed an experiment involving two strains of microorganisms, strain A and strain  B, cultured at various temperatures for 24 hours. The results of this experiment are shown in the  data table. Based on the results of the experiment, the student inferred that strain A was more  resistant to higher temperatures than strain B was. What, if anything, must the student do for this  inference to be considered valid?
    • A. 

      Nothing, because this inference is a valid scientific fact

    • B. 

      Repeat this experiment several times and obtain similar results

    • C. 

      Repeat this experiment several times and obtain different variables

    • D. 

      Develop a new hypothesis and test it

  • 15. 
    What happens to the dependent variable in a controlled experiment?  
    • A. 

      It changes as the independent variable changes

    • B. 

      It changes as the responding variable changes

    • C. 

      It does not change

    • D. 

      It is supported or disproved
