- 1. a factor which is meant to be changed in an experiment to determine the effects it has on the experiment.
- 2. something which always shows the same form or manner without variation.
- 3. an event which occurs before another event in time; something which comes before another thing regarding their positions.

- 6. a quantity which is gradually increasing with discrete additions regularly.
- 7. matter: carbon-based compounds found within natural environments and beings.
- 9. something which causes conflicting arguments; a device which is designed to cause and propagate fires.
- 11. something which forms the foundation of a system or behavior.
- 13. an organism which uses another organism as a host and feeds off the host for survival.
