You are hired by a pesticide company to determine whether its new pesticide ("Zap-em") is effective at controlling soybean aphids, an invasive species that costs American farmers millions of dollars a year in crop damage and control costs

Describe an experiment you would perform to test the effectiveness of Zap-em.


Students' answers will vary but should include all of the following components:
A. replicate plots (It would be inappropriate to test Zap-em on a single field.)
B. treatment and control plots, assigned randomly (Zap-em plots need to be compared to plots not sprayed with Zap-em.)
C. dependent variables to be measured (e.g., crop yield, amount of crop damage, and density of soybean aphids in plots)
D. use of statistical analysis to analyze the data

An element has two different isotopes: one that weighs 65 amu and another that weighs 67 amu. If the average atomic mass of all the isotopes is 66.5 amu, what can be said about the relative abundance of the isotopes?

A. All the isotopes have the same relative abundance. B. The isotope with the mass of 66.5 is more abundant than the isotope with the mass of 67. C. The isotope with the mass of 66.5 is more abundant than the isotope with the mass of 65. D. The isotope with the mass of 67 is more abundant than the isotope with the mass of 65. E. The isotope with the mass of 65 is more abundant than the isotope with the mass of 67.
