- 3. VARIABLE, The variable manipulated by the experimenter
- 5. VARIABLE, The variable responding to the manipulated variable
- 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
- 8. Organisms that eat only organisms other than plants.
- 10. GROUP, the group in an experiment that experiences no manipulation (does not contain the independent variable)
- 11. The maintenance of stable internal conditions.
- 14. LAW, a description of a natural relationship or principle, often expressed in mathematical terms, and supported by a significant amount of evidence
- 15. REPRODUCTION, Process by which a single organism produces genetically identical offspring
- 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
- 24. OBSERVATIONS, Observations involving numbers, such as counting or measuring.
- 25. The study of life. the Greek word bios means "life", and -logy means "study of".

- 1. ELECTRON MICROSCOPE, a microscope that transmits a beam of electrons through a thinly sliced specimen
- 2. Logical interpretation based on prior knowledge, experience, or evidence
- 4. The process by which physical and biological characteristics are transmitted from the parent (parents) to the offspring.
- 7. SYSTEM OF UNITS, the metric system (SI), which is the most widely used system of measurement in science

- 12. the sum total of all processes in an organism that break down chemicals to produce energy and simple chemical building blocks
- 13. The process by which green plants and some other organisms use the energy of sunlight and simple chemicals to produce their own food.
- 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.
- 18. GROUP, The group in an experiment that is manipulated
- 19. a suggested, testable answer to a well-defined scientific question or a possible, testable explanation for observations
