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






2. It spreads the work over a greater distance along the planes of the wedge.






3. An atom with an imbalanced charge






4. The capacity to work






5. The amount of matter that makes up an atom. You can estimate an atom's atomic mass by adding up the total number of protons and neutrons.






6. Angiosperms






7. As temperature increases volume also increases


8. Spiral disk with several long arms.






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






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






11. 1. positive charge 2. located in nucleus 3. mass is 1 AMU






12. That matter cannot be created or destroyed; it simply changes form.






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






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






15. Occurs when light is bent while passing from one medium into another.






16. Within compounds - the various atoms making up molecules are held together by...






17. Are caused by the gravitational pull of the Moon and the Sun on the Earth.






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






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






20. Thin - flexible barrier around a cell; regulates what enters and leaves the cell






21. Force = Mass X Acceleration






22. 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.






23. 1. convergent 2. divergent 3. transform






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






25. The quantity of substance






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






27. 1. igneous 2. metamorphic 3. sedimentary






28. Describes speed and direction






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






30. Is a change in velocity






31. Cell begins to split






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






33. 1. prophase 2. metaphase 3. anaphase 4. telophase






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






35. Is an object's rate of motion = Distance/Time






36. An isotope created in the earth's atmosphere by cosmic rays. All living things absorb carbon 14. When they die absorption stops and the organism's existing C14 begins to radioactively decay back to C12.






37. Converts energy from food to energy the cell can use






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


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






40. Control center of the cell






41. 1. State the problem. 2. Form a hypothesis. 3. Observe and experiment. 4. Interpret the data. 5. Draw conclusions.






42. H2O + CO2 --> CH2O + O2






43. Has the same number of protons and neutrons






44. A group of subjects upon which a hypothesis is tested.






45. One member benefits - the other is unaffected.






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






47. Is a homogeneous mixture in which one substance has dissolved into the other - example: salt water






48. 1. gravity 2. magnetism 3. friction (think of a falling sheet of paper vs. a falling book)






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






50. Require a medium and travel much slower than light.
