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. Both members of a symbiotic relationship benefit






2. 1. egg 2. larvae 3. pupae/crysalis 4. imago/adult butterfly






3. 1. mutualism 2. parasitism 3. commensalism






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






5. The quantity of substance






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






7. Refers to the vast periods of time over which the Earth changes.






8. The point around which a lever rotates






9. Unless an object is moving in a vacuum - the object causes...






10. Illustrates the relationship between absolute magnitude - luminosity - classification and effective temperature of stars.

12. Energy in motion






13. An atom that has a different number of neutrons than its normal amount.






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






15. 1. igneous 2. metamorphic 3. sedimentary






16. Is a substance composed of two or more elements






17. A bond in which on atom loses an electron to form a positive ion and the other gains an electron to form a negative ion - creating an electrostatic force which holds them together.

23. Cellular division to create sex cells called haploids.






24. Occurs when cooler portions of a liquid or gas flow in to take the place of hotter - rising portions.






25. The Moon and the Sun are on opposite sides of the Earth.






26. 1. solid 2. liquid 3. gas






27. Subatomic particles including: 1. protons 2. neutrons 3. electrons






28. Because carbon bonds readily with a variety of different elements and compounds - making possible the great chemical complexity necessary for life.






29. 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.






30. Causes beneficial traits to be propagated and detrimental traits to be eliminated.






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

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






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






49. Occurs when heat is transmitted in the form of electromagnetic waves.






50. The time required by half the atoms of a particular substance to disintegrate
