To predict: Which organisms produce more nitrogenous wastes—an endotherm or an ectotherm. Introduction: The metabolic wastes that contain nitrogen are known as nitrogenous waste. For example, urea and uric acid are nitrogenous waste products in terrestrial animals. The endotherms are those organisms that can maintain a constant body temperature through heat generated by its own metabolism . The ectotherms are those animals that maintain their constant body temperature by gaining heat from the surroundings or external environment. Their body temperature can vary depending upon the environment in which it is present.

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…
