CSET Subject 2: Science

Subjects : cset, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

9. Asserts that organisms have changed over time to adapt to the unique and varied demands of their changing environments.


10. Deoxyribonucleic acid






11. Matter and energy have the properties of both particles and waves






12. Is a change in velocity






13. By wind which stirs the ocean's surface of great distances.






14. Is a system in which small particles are kept dispersed by agitation or molecular motion in the surrounding medium - example: muddy freshwater

17. The capacity to work






18. An ion






19. States that all of the Earth's continents at one time were joined as a single 'super - continent' called Pangaea. Over time - the continents drifted apart.






20. Occurs when heat is transferred due to fast moving atoms and molecules colliding with slower ones in a neighboring region.






21. Caused by the Earth's tilt on its axis. As it revolves arond the Sun - the tilt causes each hemisphere to receive more direct exposure at certain times in its orbit.






22. The number of protons a particular type of atom has. The atomic number defines the type of element.
