1. Short Answer: How does the change in concentration of oil represent biomagnification?
2. Multiple Choice: How does this also illustrate the amount of energy transferred from one trophic level to the next?
A.) The volume of oil increases with each transfer as energy increases because 100% of the energy is transferred from one trophic level to another.
B.) Only a percentage of the original 10 mL of oil is transferred at each level as only a percentage of the energy in an organism is transferred.

How does a regression plane differ from a regression line? Multiple Choice A regression plane represents a two-dimensional space (e.g. one dependent and one independent variable) whereas a regression line represents a three-dimensional space (e.g. one dependent and two independent variables). A regression plane represents a three-dimensional space (e.g. one dependent and two independent variables) whereas a regression line represents a two-dimensional space (e.g. one dependent and one independent variable). A regression plane can represent a bivariate regression model and...

How does a bivariate regression model differ from a multiple regression model? Multiple Choice A bivariate regression has only one dependent and independent variable but a multiple regression has one dependent variable and may have many independent variables. A bivariate regression has more than one dependent variable and only one independent variable where a multiple regression has one dependent variable and may have many independent variables. A bivariate regression has only one dependent and many independent variables but a multiple...
