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 point around which a lever rotates






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






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






4. Control center of the cell






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






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






7. Angiosperms






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






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






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






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






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






13. Anything that has mass and takes up space






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






15. 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.






16. Cell begins to split






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






18. 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.






19. Spiral disk with several long arms.






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






21. Duplicates genetic material






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






23. C14 dating only works on organisms that died less than _____ years ago.






24. 1. hair 2. warm - blooded 3. live birth 4. nurses their young






25. Subatomic particles including: 1. protons 2. neutrons 3. electrons






26. 1. convergent 2. divergent 3. transform






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






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






29. Cellular division creating diploid cells which are typically capable of beginning the process again.






30. One member benefits - the other is unaffected.






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






32. 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.






33. When the Moon and the Sun are in alignment we get more extreme tides.






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






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






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






37. Deoxyribonucleic acid






38. 1. mutualism 2. parasitism 3. commensalism






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






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






41. As pressure increases volume decreases


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


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






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






45. An atom with an imbalanced charge






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

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






49. The capacity to work






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