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.
1. 1. negative charge 2. located in the nucleus 3. mass is about 1/1836th of an AMU






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






3. Both members of a symbiotic relationship benefit






4. 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.






5. Is something that starts a chemical reaction - such as a spark.






6. 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.






7. Is a method of separating ions within a substance by passing electrical current through the substance






8. Is a substance composed of two or more elements






9. One member benefits - the other is unaffected.






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






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






12. Stores food and other materials needed by the cell






13. The quantity of substance






14. Occurs when chemical composition of a substance is altered.






15. 1. Law of Inertia 2. Law of Acceleration 3. Law of Reciprocal Actions


16. 1. convergent 2. divergent 3. transform






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






18. Radioactively decay back into their 'normal' forms over time






19. A change in position






20. Plants response to gravity






21. 1. producer 2. primary consumer 3. secondary consumer 4. tertiary consumer 5. decomposer






22. 1. evaporation 2. condensation 3. precipitation 4. infiltration 5. runoff






23. A fairly typical main sequence star.






24. A bond formed when atoms share one or more of their valence electrons.






25. Grain like organelles that produce proteins

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






28. When the Moon or the Sun are pulling at perpendicular angles we get less extreme tides.

32. Is the particular wavelength of light we observe that is not absorbed by an object.






33. For every action there is an equal and opposite reaction.






34. Stored energy






35. As temperature increases volume also increases


36. Duplicates genetic material






37. 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.






38. Is a change from one state to another without a change in chemical composition.






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






40. Organelle found in cells of plants and some other organisms that captures the energy from sunlight and convert it into chemical energy
