部分真题预览：

1）In an investigation of fruit-fly behavior, a covered choice chamber is used to test whether the spatial distribution of flies is affected by the presence of a substance placed at one end of the chamber. To test the flies’ preference for glucose, 60 flies are introduced into the middle of the choice chamber at the insertion point indicated by the arrow in the figure above. A cotton ball soaked with a 10% glucose solution is placed at one end of the chamber, and a dry cotton ball with no solution is placed at the other end. The positions of flies are observed and recorded every minute for 10 minutes.

1. Predict the distribution of flies in the chamber after 10 minutes and justify your prediction.
2. Propose ONE specific improvement to each of the following parts of the experimental design and explain how the modification will affect the experiment.
   • Experimental control
   • Environmental factors
3. The experiment described above is repeated with ripe bananas at one end and unripe bananas at the other end. Once again the positions of the flies are observed and recorded every minute for 10 minutes. The positions of flies after 1 minute and after 10 minutes are shown in the table below.

   DISTRIBUTION OF FLIES IN CHOICE CHAMBER

   Perform a chi-square test on the data for the 10-minute time point in the banana experiment. Specify the null hypothesis that you are testing and enter the values from your calculations in the table below.

4. Explain whether your hypothesis is supported by the chi-square test and justify your explanation.
5. Briefly propose a model that describes how environmental cues affect the behavior of the flies in the choice chamber.
