1) Use the table below to determine the haploid number for each organism.

Common Name                           Ploidy                      Number of Chromosomes
          Dog                                     Diploid                                    78

     Potato                                 Tetraploid                                  48

      Shark                                    Diploid                                       82

     Wheat                                 Hexaploid                                    42

3) Global warming is an issue affecting many species around the world. Warming has caused the temperatures in lakes and rivers to increase and stay elevated for longer periods of time.

Select the numbers that describe the possible effects of global warming on the reproduction of rainbow trout in the wild and on biodiversity.

1) The extra set of chromosomes remains.
2) The extra set of chromosomes is removed.
3) The offspring are diploid (2n).
4) The offspring are triploid (3n).
5) The offspring cannot reproduce.
6) The offspring can reproduce.
7) Biodiversity decreases.
8) Biodiversity increases.

Please record the numbers in ascending order.

5) Some Events that Occur in Various Stages of Cell Division

1) DNA replication takes place.
2) Cytoplasm divides.
3) Chromosomes align at the equator of the cell.
4) Centromeres split; sister chromatids pull apart.
5) Chromosomes condense.
6) Chromatids move to opposite poles.
