No need to answer all! would be though : ) 1. state two pieces of evidence that support the idea that, "the forces that dictate ecological interactions are at play in ecosystems of all scales, from animal level to bacterial level." 2. describe an investigation/expirment that explores a factor that could affect the rate of photosynthesis. what results would your investigation produce that supports your factor affecting the rate of photosynthesis? 3. you discover two geographically isolated populations of a species that have slight differences in color. list 3 specific, testable questions that you could design an investigation around to determine why the populations display these traits. 4. how can the 4 key ideas of natural selection be used to predict how species will evolve or how an ancestor species evolved into modern species? 5. certain bird wings are developed to assist in long-distance flight. consider an albatross. these birds fly extremely long distances to hunt for food. what change in conditions could have forced the ancestor to an albatross to develop this adaptation? 6. what are 5 lines of evidence that support common ancestry in modern species? 7. how could members of a sequence of fossils that show the development of a certain trait be found in vastly different areas around the world? 8. in elephant seals, despite the fact that females prefer certain areas of the beach during mating season, they will reproduce with many males before returning to sea. what does that say about conditions driving sexual selection in males?
