- 12. organisms that depend on other organisms for their food
- 13. the process by which physical and biological characteristics are transmitted from the parent (or parents) to the offspring
- 14. the sum total of all processes in an organism that break down chemicals to produce energy and simple chemical building blocks
- 15. law, a description of a natural relationship or principle, often expressed in mathematical terms, and supported by a significant amount of evidence
- 16. a carefully thought-out explanation for observations of the natural world that has been constructed using the scientific method, and which brings together many facts and hypotheses

Down
- 1. organisms that eat only plants
- 3. organisms that are able to make their own food
- 4. the process by which preen plants aand some other organisms use the energy of sunlight and simple chemicals to produce their own food
- 5. the idea that long ago, very simple life forms spontaneouslyappeared through chemical reactions
- 6. logical interpretation based on prior knowledge, experience, or evidence
- 8. an abrupt and marked change in the DNA of an organism compared to that of its parents
- 10. 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 organisms life functions
- 11. the collected body of data from experiments and observations
- 17. special structures that allow living organisms to sense the conditions of their internal or external enviroment
- 20. group, the group in an experiment that is manipulated (contains the independent variable)
- 21. group, the group in an experiment that experiences no manipulation (does not contain the independent variable)
- 22. the sum total of all processes in an organism that use energy and simple chemicle building blocks to produce large chemicals and structures necessary for life
- 24. light microscope, a microscope that shines light through a specimen using two lenses to magnify an image
- 25. electron microscope, a microscope that passes a beam of electrons over the surface of a specimen
- 26. organism that is internally warmed by a heat-generating metabolic process
- 27. a factor that changes in an experiment
- 28. reproduction, process by which a single oranism produces genetically identical offspring(offspring recieves all DNA from one parent)
- 30. reproduction, process by which two parents produce genetically different offspring (offspring receives a combination of DNA from two parents)
