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.

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






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






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






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






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






7. 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.

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






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






11. Is a system in which small particles are kept dispersed by agitation or molecular motion in the surrounding medium - example: muddy freshwater

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






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






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






18. Converts energy from food to energy the cell can use






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






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






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






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






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






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






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






26. Is a change in velocity






27. Cell begins to split






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

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






35. Is the process of storing energy through photosynthesis and later releasing it through respiration.






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






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






38. Both members of a symbiotic relationship benefit






39. Spiral disk with several long arms.






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

42. Deoxyribonucleic acid






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






44. Protects and supports the cell






45. 1. mutualism 2. parasitism 3. commensalism






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






47. One member of a symbiotic relationship benefit.






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






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






50. The capacity to work
