Sample QuestionThe figure to the right describes the evolution of drug resistance in HIV where the drug is a reverse transcriptase inhibitor. Notice that all 3 colored lines begin on the left axis at a point above 0 % of HIV resistant to 3TC. What is the significance of the observation that the number is greater than zero?

Sample QuestionAs a consequence of size alone, organisms that are large tend to have larger brains than organisms that are small. However, some organisms have brains that are considerably larger than expected for an animal of their size. Data for 14 bird species are listed below. Graph the data and then, based on the data, determine which of the statements below is most reasonable. Deviation from expected brain size, that is the brain size based on body mass alone. (Negative values indicate grain sizes smaller than expected; positive values indicate brain sizes larger than expected.) -1.8 1.2 3.2 -2.4 0.0 -2.0 2.3 2.0 -1.0 -2.1 0.3 3.0 1.3 0.7 Mortality rate 0.9 0.8 0.6 0.9 0.7 0.5 0.6 0.6 0.4 0.7 0.8 0.3 0.3 0.4
