Your example must be different from the classic “liquid in different cups” conservation task.

Extra Credit Question (3 points) Suppose a scientist measures the amount of DNA per cell of a particular diploid species at various stages of meiosis. She finds that the meiotic cells contain 3.7 pg, 7.3 pg or 14.6 pg of DNA per cell. Specify the amount of DNA per cell (3.7 pg, 7.3 pg or 14.6 pg) for cells in the following stage of the cell cycle: Stage of the Cell Cycle Amount of DNA per cell G2 After Cytokinesis of Meiosis II Metaphase of Meiosis II
