  10. ·        
    If a plant was removing carbon dioxide
    from the air during the day, could it be a C4 plant?
    • ·

  11. ·        
    Name the four phases of mitosis in order.
    • ·        
    • prophase, metaphase, anaphase, telophase

    Which phase of mitosis has the sister
    chromatids separating?

    have the same genes, but are not identical: sister chromatids or homologous
    • ·        
    • homologous chromosomes
  14. ·        
    True or false: Independent orientation of
    chromosomes means that all of the chromosomes from one parent are attached

  24. If
    the chance of being tall was 1/3 and the chance of being green-eyed is 1/3,
    what is the change of being tall AND green-eyed?
