  1. 2. A population that grows without limit
  2. 4. Study of the form of living things
  3. 6. The process by which cells use oxygen to break down glucose and release energy (ATP).Theory, A well tested scientific explanation supported by lots of evidence.
  4. 7. Mechanism of evolution that occurs when random change in the allele frequency happens in the population
  5. 10. A species whose presence or absence shows the health of an environment.
  6. 18. Evolutionary history of a species
  7. 19. The factor that is measured in an experiment.
  8. 22. When there are no changes in the allele frequencies in a population over time, and thus evolution is not occurring
  9. 24. A process that does not require oxygen.
  10. 27. Balance between Earth’s resources, human needs, and the needs of other species
  11. 32. The number of individuals of a species living in a specific area.
  12. 35. Mechanism of evolution caused by the movement of genes into or out of a population
  13. 36. When a body of water becomes overly enriched with nutrients, causing excessive algae growth
  14. 37. The movement of a particular form of matter through the living and nonliving parts of an ecosystem
  15. 38. The process by which new species form over time.
  16. 39. The role or job an organism has in its ecosystem, including how it gets food and interacts with other organisms.
  17. 40. Data that is measured in numbers (example: temperature, height, time).
  18. 41. A process cells use to release energy from food without oxygen.
  19. 42. 2name naming system by Carolus Linnaeus that names organisms after their Genus species
Down
  1. 1. Study of embryo development
  2. 3. Study of the geographic distribution of plants and animals
  3. 5. Greater impact on a more dense population
  4. 8. Small scale evolution affecting a single population
  5. 9. A factor that stays the same during an experiment.
  6. 11. Measure of the number of organisms living in a defined area
  7. 12. A type of divergent evolution occurring on a small scale over a shorter period of time
  8. 13. Data that is described using words (example: color, texture, smell).
  9. 14. Species that exist only in one geographic region
  10. 15. The factor that is changed in an experiment.
  11. 16. Impact is independent of population density, therefore the same impact on more dense and less dense populations
  12. 17. A process that requires oxygen.
  13. 20. When one prokaryote ended up inside another and both organisms thrived
  14. 21. A measure of how well an organism can survive in its environment
  15. 23. A feature that allows an organism to better survive in its environment
  16. 25. Mechanism of evolution that favors traits that potentially decrease survival, but increase likelihood of reproduction
  17. 26. A graphic representation of mortality patterns, showing the number of individuals in a population that can be expected to survive to any specific age
  18. 28. Mechanism of evolution where organisms with the “best” traits are favored and thus live longer and reproduce more, causing changes in the population over time so that the fittest survive
  19. 29. A testable prediction or educated guess based on observations.
  20. 30. A population that grows quickly at first but levels off at the carrying capacity due to limited resources
  21. 31. Nonfunctional genes
  22. 33. Study of chemical processes in living things
  23. 34. The combined alleles of all individuals in a population
