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






2. Our solar system is made up of numerous bodies which orbit the Sun due to...






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






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






5. H2O + CO2 --> CH2O + O2






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






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






8. Both members of a symbiotic relationship benefit






9. 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.






10. 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.






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






12. The types of organisms an ecosystem can support is primarily determined by the amount of...






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






14. Anything that has mass and takes up space






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






16. Is the measure of the presence of hydrogen ions in a substance.






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






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






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






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






21. 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.






22. 1. igneous 2. metamorphic 3. sedimentary






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






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






25. Protects and supports the cell






26. Plants response to light






27. A fairly typical main sequence star.






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






29. Control center of the cell






30. That space and time are relative - not absolute concepts






31. One member benefits - the other is unaffected.






32. Force = Mass X Acceleration






33. Phase where spindle grows and which cuts the cell






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






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






36. Plants response to gravity






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






38. Pulls apart into two separate cells






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






40. An object in motion stays in motion along a straight path unless acted upon by a net external force.






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






42. The point around which a lever rotates






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






44. 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.






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






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

48. Matter and energy have the properties of both particles and waves






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