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. inner core 2. outer core 3. mantle 4. crust






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






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






4. Grain like organelles that produce proteins






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






6. 1. convergent 2. divergent 3. transform






7. 1. temperature (think movement) 2. pressure






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






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






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






11. An atom with an imbalanced charge






12. 1. neutral charge 2. located in the nucleus 3. mass is 1 AMU






13. Has the same number of protons and neutrons






14. Is a substance composed of two or more elements






15. Stamen






16. Describes speed and direction






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


18. 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.






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






20. 1. egg 2. tadpole (breathes water) 3. metamorphosis 4. adult frog (breathes air)






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






22. 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. H2O + CO2 --> CH2O + O2






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






25. A material that can be separated by physical means into two or more substances.






26. 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.






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






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






29. Cellular division to create sex cells called haploids.






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






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






32. Forms the key building block at an atomic level.






33. 1. the more massive either or both bodies are - the greater the gravitational force between them. 2. the further apart two bodies are - the lesser the gravitational force between them.






34. As temperature increases volume also increases


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






36. As pressure increases volume decreases


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






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






39. A fairly typical main sequence star.






40. Calories






41. Are affected by the angle from which we view the moon.






42. Are huge clusters of billions of stars






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






44. Force = Mass X Acceleration






45. Duplicates genetic material






46. 1. incline plane2. wheel and axle 3. lever 4. pulley 5. wedge 6. screw






47. 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.






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






49. Material inside the cell membrane -- not including the nucleus






50. The capacity to work
