         1   The diagram below represents the nitrogen cycle in a student’s aquarium. Ammonia,
             nitrites, and, to a lesser degree, nitrates can be harmful to fish. The student wants to keep
             the nitrogen in this aquarium cycling normally without having to continually change the
             water.
             Which of the following should the student add more of to help remove nitrates and improve
             the natural cycling of nitrogen in this aquarium?
             A Fish
             B Plants
             C Nitrobacter
             D Water

                                                           any leftover iodine solution from the
             F proven right or proven

          4 If new information brought about by          7 Which of the following is true for a
             new technology disproves a theory,             scientific theory?
             what will happen to the theory?
                                                            A capable of making valid predictions
             F Nothing, theories are always right.

             J   The theory will become a
                 hypothesis.
          5 Which material should be disposed of
             after a lab, rather than being reused or
             recycled?
             A Test tube that had held salt water
             B Cotton swab used to collect cheek
                 cells

                 alcohol
          6 Which of the following represents a
             factor that limits a population and is
             dependent on the population density?
