True 7. False (Eukaryotic cells are generally more complex and larger than prokaryotic cells.) 8. True 9. Cyanobacteria are significant because they were among the first organisms to perform photosynthesis, which produced oxygen and contributed to the Great Oxygenation Event, dramatically changing the atmosphere and enabling aerobic life. 10. Coal is formed from ancient plant material in swampy environments under high pressure over millions of years, while oil is derived from the remains of marine organisms and forms in sedimentary rock under heat and pressure. Coal is generally found in lower latitudes, whereas oil deposits can be more widely distributed. 11. Drake 12.

The trend observed during the late Paleozoic era typically shows a significant increase in diversity followed by a sharp decline due to the Permian mass extinction event, which is often attributed to volcanic activity and climate changes.

What are the two main hypotheses regarding the origin of life on Earth? Briefly describe each. 10. Describe the role of plate tectonics in shaping Earth’s paleogeography. Fill in the Blank Questions 11. The first complex cells, which contain a nucleus, are referred to as ___________. 12. The phenomenon where Earth experienced extensive glaciation at the equator is known as ___________. Matching Questions 13. Match the following terms to their definitions: a) Eukaryote b) Prokaryote c) Endosymbiosis d) Chemosynthesis 1) Process by which certain organisms produce energy from inorganic molecules 2) Organism with a defined nucleus 3) Organism without a defined nucleus 4) Theory explaining the origin of mitochondria and chloroplasts Graph Interpretation Question 14. Refer to a graph showing the fossil record of major taxonomic groups. What significant pattern do you see regarding trilobites and their extinction? What does this suggest about their ecological role? --- Answer Key 1. d) Atmospheric sampling 2. b) Accretion and outgassing 3. b) Aerobic respiration requires oxygen; anaerobic does not 4. b) Eukaryotes 5. b) Jurassic 6. False (The Drake equation estimates the number of communicative extraterrestrial civilizations.) 7. True 8. True 9. The two main hypotheses regarding the origin of life are: - RNA world hypothesis: Proposes that self-replicating RNA molecules were the precursors to current life. - Iron-sulfur world hypothesis: Suggests that life originated on the surface of iron and nickel sulfide minerals in hydrothermal vents. 10. Plate tectonics plays a crucial role in shaping Earth’s paleogeography by causing the movement of continents, which affects climate, ocean currents, and the distribution of ecosystems over geological time. This movement also creates geological features like mountains and ocean basins. 11. Eukaryotes 12. Snowball Earth 13. a) 2 (Organism with a defined nucleus) b) 3 (Organism without a defined nucleus) c) 4 (Theory explaining the origin of mitochondria and chloroplasts) d) 1 (Process by which certain organisms produce energy from inorganic molecules) 14. The graph likely shows a sharp decline in trilobite diversity during the late Paleozoic, indicating a mass extinction event. This suggests that trilobites played a significant role in marine ecosystems before their extinction. Multiple Choice Questions 1.
