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. by row 2. atomic number and mass increase as you move left to right and top to bottom






2. 1. solid 2. liquid 3. gas






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






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






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






6. 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.






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






8. As a nebula contracts - the particles collide with colossal force igniting a nuclear reaction and forming a protostar.






9. Calories






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






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

13. 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.






14. Plants response to gravity






15. 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.






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






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






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






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






20. As temperature increases volume also increases

21. An atom with an imbalanced charge






22. Occur because the shadow of the Earth or the Moon is cast onto the other body.






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






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






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






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






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






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






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






30. 1. igneous 2. metamorphic 3. sedimentary






31. Angiosperms






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






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






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






35. 1. homeostasis 2. organization 3. metabolism 4. growth 5. adaptation 6. response to stimuli 7. reproduction






36. The Moon is between the Earth and the Sun.






37. The capacity to work






38. Protects and supports the cell






39. Describes speed and direction






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






41. 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.






42. An ion






43. Control center of the cell






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






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






46. Energy in motion






47. Cell begins to split






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






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