SCIENTIFIC THINKING Another aspect of the Nurses’ Health Study introduced in Module 3.9 looked at the percentage of change in the risk of coronary heart disease associated with substituting one dietary component for another. These results estimated that replacement of 5% of energy from saturated fat in the diet with unsaturated fats would reduce the risk of heart disease by 42%, and that the replacement of 2% of energy from trans fat with unsaturated fats would reduce the risk by 53%. Explain what these numbers mean.

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?
