  1. 2. reproduction Process by which two parents produce genetically different offspring.
  2. 4. Organisms that depend on other organisms for their food
  3. 6. 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
  4. 9. The collected body of data from experiments and observations.
  5. 11. variable The variable manipulated by the experimenter
  6. 13. 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.
  7. 14. A factor that changes in an experiment
  8. 16. theory 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
  9. 19. The process by which physical and biological characteristics are transmitted from the parent (parents) to the offspring.
  10. 21. Living creatures that are too small to see with the naked eye
  11. 22. electron microscope A microscope that transmits a beam of electrons through a thinly sliced specimen
  12. 25. Special structures that allow living organisms to sense the conditions of their internal or external environment.
  13. 26. The smallest units of an organism considered alive
  14. 27. variable The variable responding to the manipulated variable
  15. 28. Idea that long ago, very simple life forms spontaneously appeared through chemical reactions
  16. 34. light microscope A microscope that shines light through a specimen using two lenses to magnify an image
  17. 35. Logical interpretation based on prior knowledge, experience, or evidence
  18. 36. A suggested, testable answer to a well-defined scientific question or a possible, testable explanation for observations
  19. 37. The maintenance of stable internal conditions.
  20. 38. Organisms that only eat plants.
Down
  1. 1. An abrupt and marked change in the DNA of an organism compared to that of its parents
  2. 3. group The group in an experiment that is manipulated
  3. 5. electron microscope A microscope that passes a beam of electrons over the surface of a specimen
  4. 7. observations Observations involving numbers, such as counting or measuring.
  5. 8. reproduction Process by which a single organism produces genetically identical offspring
  6. 10. observations Observations that are not easily counted or measured, such as color or texture
  7. 12. The sum total of all processes in an organism that break down chemicals to produce energy and simple chemical building blocks
  8. 15. The process by which green plants and some other organisms use the energy of sunlight and simple chemicals to produce their own food.
  9. 17. control The group in an experiment that experiences no manipulation (does not contain the independent variable)
  10. 18. system of units The metric system (SI), which is the most widely used system of measurement in science
  11. 20. law A description of a natural relationship or principle, often expressed in mathematical terms, and supported by a significant amount of evidence
  12. 23. The Latin prefix uni means "one", so unicellular means "single-celled"
  13. 24. Organism that is internally warmed by heat-generating metabolic process.
  14. 29. The study of life. the Greek word bios means "life", and -logy means "study of".
  15. 30. Organisms that eat both plants and other organisms.
  16. 31. Organisms that are able to make their own food
  17. 32. Organisms that eat only organisms other than plants.
  18. 33. Organism that lacks an internal mechanism for regulating body heat
