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.
1. Are a progressive disturbance propagated from point to point (with regularity between points)






2. Begin as huge clouds of dust and other particles called nebulas.






3. Energy changes forms but is not created or destroyed.






4. Is the smallest unit of an element that still has the properties of that element.






5. Column

20. A fairly typical main sequence star.






21. Grain like organelles that produce proteins






22. Is a substance that cannot be separated into simpler substances by chemical means






23. Pulls apart into two separate cells






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

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






40. Can occur by chemical means such as acid rain or physical means - such as wind - rain and ice.






41. Has the same number of protons and neutrons






42. Plants response to light






43. A group which resembles the experimental group in all other ways - but on which the hypothesis is not tested. In some clinical trials the control group is given a placebo.
