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.

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






8. Cell begins to split






9. This is the motion of objects emitting or reflecting sound waves changing their frequency.






10. Cellular division creating diploid cells which are typically capable of beginning the process again.






11. The quantity of substance






12. Occurs when light returns after bouncing off an object.
