To draw: The three possible dichotomously branching phylogenetic trees showing evolutionary relationships between the three domains: Bacteria, Archaea, and Eukarya. Introduction: The phylogenetic tree can be constructed from DNA sequences or morphological study. The organism that shares a very similar morphology, or DNA sequences are most likely to be the descendant from a common ancestor. The closely-related organisms that are immediately descended from a common ancestor is called the sister group.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.) Data Table 1Stage Totals PercentInterphase Mitosis: Prophase Metaphase Anaphase Telophase Cytokinesis Totals 100 100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours. (Example: If percent is 20%, then Time in Hours = .2 * 24 = 4.8) Record your data in Data…
