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






2. Anything that has mass and takes up space






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

15. The point around which a lever rotates






16. Causes salt to move across a permeable membrane from an area of greater salinity to an area of lesser salinity.






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






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






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






20. Cell begins to split






21. 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.






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






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






24. Protects and supports the cell






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






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






27. Both members of a symbiotic relationship benefit






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






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






30. 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.






31. The measure of the kinetic energy in a substance's molecules. Simply - temperature is atomic motion.






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






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






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






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






36. 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.






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






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






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






40. Column






41. Energy in motion






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






43. Describes speed and direction






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






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






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






47. Spiral disk with several long arms.






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






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






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