    A scientist performs an experiment to determine the effect of temperature on the developmental time of flies. (Larva to adult fly)Which of the following would most likely be true? 
    • A. 

      There is a direct relationship between temperature and developmental time of flies

    • B. 

      The rate of cell division is faster at the increased temperature.

      A cell grows in size.

    • C. 

      The number of organelles increases.

    Emmet noticed that his tarantula had molted (it shed off its outer skin) and now was larger in size than when he first received his pet. Which explanation BEST describes what happened? 
    • A. 

      Parts of the tarantula stretched as it grew larger.

    • B. 

      The tarantula ate food and water.

    • C. 

      The total number of cells in the tarantula increased.

    • D.

  • 6. 
    A dog will have 78 chromosomes in its nucleus. During the S phase of the cell cycle_____ number of chromatids will be in the nucleus and after mitosis (and cytokinesis) _____ number will be present in the nucleus.
    • A. 

      156; 78

    • B. 

      78;78

    • C. 

      78; 156

    • D. 

      39;78

  • 7. 
    Look at the data table below showing the diploid number of chromosomes in various organism. Which of the following is the best explanation for why each of these organisms have a even number of chromosomes? 
    • A. 

      It is only a coincidence; many organisms have an odd number of chromosomes.

    • B. 

      Chromosomes double each time a cell divides; so after the first division, the number will always be even.

    • C. 

      The diploid number represents a pair of chromosomes -- one from each parent -- so it will always be an even number.

  • 8.
