  1. 3. VARIABLE, The variable manipulated by the experimenter
  2. 5. VARIABLE, The variable responding to the manipulated variable
  3. 6. 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
  4. 8. Organisms that eat only organisms other than plants.
  5. 10. GROUP, the group in an experiment that experiences no manipulation (does not contain the independent variable)
  6. 11. The maintenance of stable internal conditions.
  7. 14. LAW, a description of a natural relationship or principle, often expressed in mathematical terms, and supported by a significant amount of evidence
  8. 15. REPRODUCTION, Process by which a single organism produces genetically identical offspring
  9. 17. 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
  10. 24. OBSERVATIONS, Observations involving numbers, such as counting or measuring.
  11. 25. The study of life. the Greek word bios means "life", and -logy means "study of".
  12. 26. OBSERVATIONS, Observations that are not easily counted or measured, such as color or texture
  13. 28. Organisms that only eat plants.
  14. 29. REPRODUCTION, Process by which two parents produce genetically different offspring.
  15. 32. organisms that are able to make their own food
  16. 33. living creatures that are too small to see with the naked eye
  17. 35. Organisms that eat both plants and other organisms.
  18. 36. The smallest units of an organism considered alive
  19. 37. organism that lacks an internal mechanism for regulating body heat
  20. 38. an abrupt and marked change in the DNA of an organism compared to that of its parents

  1. 1. ELECTRON MICROSCOPE, a microscope that transmits a beam of electrons through a thinly sliced specimen
  2. 2. Logical interpretation based on prior knowledge, experience, or evidence
  3. 4. The process by which physical and biological characteristics are transmitted from the parent (parents) to the offspring.
  4. 7. SYSTEM OF UNITS, the metric system (SI), which is the most widely used system of measurement in science
  5. 9. The idea that long ago, very simple life forms spontaneously appeared through chemical reactions
  6. 12. the sum total of all processes in an organism that break down chemicals to produce energy and simple chemical building blocks
  7. 13. The process by which green plants and some other organisms use the energy of sunlight and simple chemicals to produce their own food.
  8. 16. 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.
  9. 18. GROUP, The group in an experiment that is manipulated
  10. 19. a suggested, testable answer to a well-defined scientific question or a possible, testable explanation for observations
  11. 20. The Latin prefix uni means "one", so unicellular means "single-celled"
  12. 21. ELECTRON MICROSCOPE, a microscope that passes a beam of electrons over the surface of a specimen
  13. 22. Organisms that is internally warmed by heat-generating metabolic process.
  14. 23. organisms that depend on other organisms for their food
  15. 27. The collected body of data from experiments and observations.
  16. 30. LIGHT MICROSCOPE, a microscope that shines light through a specimen using two lenses to magnify an image
  17. 31. A factor that changes in an experiment
  18. 34. Special structures that allow living organisms to sense the conditions of their internal or external environment.
