Across
  1. 4. a factor that changes an experiment
  2. 7. the sum total of all processes in an organism that convert energy and matter from outside sources and use that energy and matter to sustain the organism's life functions.
  3. 9. a microscope that passes a beam of electrons over the surface of a specimen
  4. 12. a factor that is manipulated or changed in an experiment to find the results
  5. 16. a factor that is measured or recorded in an experiment as the result
  6. 17. an explanation of some part of the natural world that has been thoroughly tested and is supported by a significant amount of evidence from observations and experiments
  7. 19. organisms that eat both plants and other organisms
  8. 22. organisms that eat only organisms
  9. 23. A suggested, testable answer to a well-defined scientific question or a possible, testable explanation for observations.
  10. 24. the process by which physical and biological characteristics are transmitted from the parent to the offspring
  11. 25. living creatures that are too small to see with the naked eye
  12. 26. process by which a single organism produces offspring (offspring receives all DNA from one parent)
  13. 28. special structures that are lining organisms to sense the conditions of their internal or external environment
  14. 29. organisms that depend on other organisms for their food
  15. 30. organisms that eat only plants
  16. 31. organisms that are able to make their own food
Down
  1. 1. the sum total of all processes in an organism that use energy and simple chemical building blocks to produce large chemicals and structures necessary for life
  2. 2. the idea that long ago, very simple life forms spontaneously appeared through chemical reactions
  3. 3. the process by which green plants and some other organisms use the energy of sunlight and simple chemicals to produce their own food
  4. 5. the group in an experiment that is manipulated (contains the independent variable)
  5. 6. an abrupt and marked change in the DNA of an organism compared to that of its parents
  6. 8. the sum total of all processes in an organism that break down chemicals to produce energy and simple chemical building blocks
  7. 10. a description of a natural relationship or principle, often expressed in mathematical terms, and supported by a significant amount of evidence
  8. 11. process by which two parents produce genetically different offspring
  9. 13. a microscope that transmits a beam of electrons through a thinly sliced specimen
  10. 14. a microscope that shines light through a specimen using two lenses to magnify an image
  11. 15. the metric system, which is the most widely used system of measurement in science
  12. 18. organism that is internally warmed by a heat-generating metabolic process
  13. 20. organisms that lacks an internal mechanism for regulating body heat
  14. 21. the maintenance of stable internal conditions
  15. 27. the group in an experiment that experiences no manipulation(does not contain the independent variable)
