Part 1: Population A Directions: Refer to the “Pop A Prey Density” sheet, which contains Population A’s prey densities from 1971 to 2020 (sample size = 50 years). Use Excel for calculations, modeling, and graphing a frequency distribution of Population A’s prey density.

Part 2: Population B Directions: Refer to the “Pop B Prey Density” sheet, which contains Population B’s prey densities from 1971 to 2020 (sample size = 50 years). Use Excel for calculations, modeling, and graphing a frequency distribution of Population B’s prey density.

Calculate the standard deviation of the line of best fit of the linear relationship between the prey density and the growth rate during the past 50 years.

What formula did you use to calculate the probabilities that growth is >0?

STEP 1: DETERMINE HOW THE CONCENTRATION OF LDL CHOLESTEROL MIGHT EXCEED THE MAXIMUM RECOMMENDED FOR HEALTH Given cholesterol’s importance to our cells, it should be no surprise that the human body has a homeostatic system to regulate cholesterol concentration in the blood.  Figure 2, long description Figure 2. This figure illustrates two pathways regulating LDL cholesterol levels in humans: one inside the liver and one outside the liver. The regulated variable, LDL cholesterol concentration in the blood, is shown in a dashed blue box at the center. Pathway 1 highlights how liver cells manage cholesterol by importing it, converting it to bile salts, and reducing blood LDL levels. Pathway 2 shows how non-liver cells interact with LDL cholesterol by importing and exporting it, which can further influence blood cholesterol levels. Plus and minus symbols on the arrows indicate positive and negative relationships between variables. Analyze the path model in Figure 2 to determine what could cause a high concentration of LDL cholesterol in a person’s blood.
