Chapter 15, Problem 2CS

Six months pregnant, an expectant mother had a routine ultrasound that showed that the limbs of the fetus were unusually short. Her physician suspected that the baby might have a genetic form of dwarfism called achondroplasia, an autosomal dominant trait occurring with a frequency of about 1 in 27,000 births. The parents were directed to a genetic counselor to discuss this diagnosis. In the conference, they learned that achondroplasia is caused by a mutant allele. Sometimes it is passed from one generation to another, but in 80 percent of all cases it is the result of a spontaneous mutation that arises in a gamete of one of the parents. They also learned that most children with achondroplasia have normal intelligence and a normal life span.

It has been suggested that prenatal genetic testing for achondroplasia be made available and offered to all women. Would you agree with this initiative? What ethical considerations would you consider when evaluating the medical and societal consequences of offering such testing?

Topic: Benthic invertebrates as an indicator species for climate change, mapping changes in ecosystems (Historical Analysis & GIS)  What objects or events has the team chosen to analyze? How does your team wish to delineate the domain or scale in which these objects or events operate? How does that limited domain facilitate a more feasible research project? What is your understanding of their relationships to other objects and events? Are you excluding other things from consideration which may influence the phenomena you seek to understand? Examples of such exclusions might include certain air-born pollutants; a general class of water bodies near Ottawa, or measurements recorded at other months of the year; interview participants from other organizations that are involved in the development of your central topic or issue.   In what ways do your research questions follow as the most appropriate and/or most practical questions (given the circumstances) to pursue to better understand…
The Esp gene encodes a protein that alters the structure of the insulin receptor on osteoblasts and interferes with the binding of insulin to the receptor. A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant). The researcher then exposed the mutant strain and a normal strain that expresses Esp to glucose and compared the levels of insulin in the blood near the osteoblasts (Figure 2). Which of the following claims is most consistent with the data shown in Figure 2 ? A Esp expression is necessary to prevent the overproduction of insulin. B Esp protein does not regulate blood-s
Predict the per capita rate of change (r) for a population of ruil trees in the presence of the novel symbiont when the soil moisture is 29%.   The formula I am given is y= -0.00012x^2 + 0.0088x -0.1372. Do I use this formula and plug in 29 for each x variable?
