Chapter 27, Problem 5CCS
23-Year-Old Female with Menstrual Irregularity
Jasmine Herrera, 23, has been referred to the endocrinology clinic. She is very overweight, with obvious acne and facial hair. She complains of irregular menstrual cycles. “My husband and I want to use the rhythm method," she says, “but I don’t have any rhythm!”
5. Jasmine’s blood tests reveal very high levels of androgens. She is diagnosed with polycystic ovary syndrome (PCOS). In this syndrome, the woman develops high levels of androgens and many vesicular follicles, but has reduced fertility because few follicles are ovulated and the timing of their release is unpredictable. Part of the profile of PCOS is that LH levels are high. How would this lead to androgen excess, and what clinical evidence of androgen excess does Jasmine have?

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…

- PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population?

You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forward
