Because marks in certain locations may be more likely to attract predators or cause problems than marks in other locations, the goal is to determine whether the six marking locations result in equivalent chances of successful migration. To test this, researchers plan to mark 3,600butterflies and release them, then count how many arrive displaying each marking location at the end of the migratory path. 20. **What type of butterfly is represented in the figure? 21. How many butterflies does the researcher plan to mark and release? 22. **Why do the researchers need to mark butterflies in different locations? B. Describe location D on the butterfly. 4. How is location A different from location D? Why do researchers mark wildlife? 5. What is the goal of the study?
