The levels of corticosterone after the release after a restraint is different in habituated and nonhabituated penguins. Corticosterone levels of both the penguins when they were captured, were similar. However, after the release, the level differed. Introduction: Corticosterone is a glucocorticoid, major stress hormone, present in many species of amphibians, reptiles, rodents, and birds, and it is mainly involved in energy regulation, immune reactions, and stress responses. The level of corticosterone differs in both the habituated and nonhabituated penguins on the basis of response levels. Stress hormones are released in the response to a threat. The physiological and behavioral mechanism developed in penguins is due to an evolutionary mechanism. Habituated penguins do not perceive humans as a threat, but nonhabituated perceive humans as a threat.

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…
