38.Populations of amphibians, including frogs and toads, have been plagued by disease and high rates of deformity.A recent study investigated whether problems among the populations have arisen due to poisons from chemicalsassociated with agriculture. Biologists from the University of Florida collected local adult cane toads (Bufo marinus)from more than 20 different locations. Toads were collected from areas close to agriculture; both large-scale andsmall-scale farms as well as from suburbs. At collection sites where 50-97% of the adjacent land was farmed,males showed high levels of feminization. Feminized male toads were similar in color to females and had lowerlevels of testosterone and often also deformed gonads. These changes can lead to sterile males or changes inbehavior that prevent mating from occurring. Which of the following statements would be considered a hypothesisfor this study?A. Amphibian populations are facing problems due to agricultural chemicals.B. Toxins are causing diseases and deformities within many amphibian populations.C. Toads collected from suburbs had fewer deformities compared to toads collected from agricultural areas.D. Agricultural chemicals cause deformities and feminization amongst cane toads.E. More male toads from the large-scale agricultural areas showed signs of feminization.39.Populations of amphibians, including frogs and toads, have been plagued by disease and high rates of deformity.A recent study investigated whether problems among the populations have arisen due to poisons from chemicalsassociated with agriculture.

24.Martin keeps a worm bin in his basement because they need cooler temperatures to survive. He feeds themabout 1 pound of kitchen scraps each week. One summer the temperatures rise above the optimal temperaturefor the red worms (~ 85°F) and many in his colony die. However, those that survive continue to reproduce andwithin 6 months his colony is again thriving. The next summer, unusually warm temperatures again cause thebasement temperatures to rise above 85°F for 2 days in a row. Surprisingly, Martin noticed that only a smallportion of the worm colony died. What is the best explanation for this?A. After the first summer a new species of worm evolved.B. The worms sensed that the temperature was going to be hot in the future and adapted.C. The worms learned how to tolerate higher temperatures.D.
