Select the prey density that best matches the biologists’ goals in the above-mentioned paragraphs. 

Choose the answer that best explains your answer to Question 23. Assume two things when answering this question. Assume the relationship between prey density and the growth rate stays the same indefinitely, AND the prey density for both populations continues to equal their typical prey densities indefinitely.

Create a plot of the frequency distribution. Does a normal probability distribution reasonably model the prey density of Population B from 1971 to 2020?

Scenario You are a member of a committee formed to review recommendations for standard medical treatments. Your subcommittee has been assigned to evaluate two common dietary treatments for people with a high concentration of LDL cholesterol – a diet low in cholesterol or a diet low in saturated fats. Additionally, we need your subcommittee to evaluate and recommend an appropriate dose of a drug called statin, which has been shown to help reduce LDL cholesterol. 

Scenario The National Park Service has monitored two populations of locally endangered owls for 50 years. From 1971 to 2020, park service biologists measured each population’s growth rate and prey density to ensure that the owl populations persist for many years to come.  Congress recently allocated funds to the National Park Service to protect this owl species. Unfortunately, the new budget is sufficient to protect only one of the two populations. The biologists read studies about interventions to save similar species of birds and concluded that increasing the prey density would be a simple yet effective strategy to protect these owls. The biologists need to determine which population they should supply with additional prey. Naturally, they wanted to invest their resources in the population that is growing at a slower rate in 2021 (in other words, the population that does not have a positive growth rate in 2021 or, if both have negative growth rates – the population with the lower growth rate). Your job is to recommend which population the biologists should protect and to determine how much prey must be added to stabilize the population.

STEP 2: DETERMINE WHICH DIET BETTER REDUCES THE CONCENTRATION OF LDL CHOLESTEROL IN A PERSON’S BLOOD  For many years, the medical community has advocated a diet that limits cholesterol and saturated fats, which are common in meat, dairy, and fried foods. However, foods such as eggs and shrimp have a large amount of cholesterol but little saturated fat. Should a person with high cholesterol avoid consuming such foods?  To answer this question, you must determine whether cholesterol concentration in a person’s blood depends on the amount of cholesterol or the amount of saturated fats consumed in their diet. You have access to data from an experiment in which 50 people with very high concentrations of LDL cholesterol followed a controlled diet for 3 months. Individuals were assigned to one of two treatments: 1) a diet low in cholesterol or 2) a diet low in saturated fats. A blood sample was taken from each person at the experiment’s beginning and end. The concentration of LDL cholesterol in each blood sample was measured using a standard protocol.  Researchers then calculated the change in LDL cholesterol (Δ) for each person by subtracting the initial concentration from the final concentration:

Select the figure that best illustrates the pattern one should observe if the biologists thought they should invest their resources into Population 1 instead of Population 2. 

Step 3 – Evaluate how statins help reduce the concentration of LDL cholesterol in a person’s blood and recommend an appropriate statin dose. Directions: Use Figure 3 to answer questions. The last question has multiple steps. First, calculate the change in the rate at which cholesterol is converted to bile salts needed to achieve this reduction. Next, determine the change in the rate at which liver cells import cholesterol required to produce the calculated change in bile salt conversion. Finally, the relationship between statin dosage and the rate of cholesterol import into liver cells is used to calculate the necessary dosage of the drug. Express your answer as a whole number. For example, if you calculate a probability of 243.54, report a value of 244.
