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. A change in position






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






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






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






5. Is a change in velocity






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






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.






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






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






10. Protects and supports the cell






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

15. 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.






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






17. 1. solid 2. liquid 3. gas






18. Plants response to light






19. Angiosperms






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






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






22. 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.






23. Is a substance that cannot be separated into simpler substances by chemical means






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






25. Stores food and other materials needed by the cell






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






27. The quantity of substance






28. As temperature increases volume also increases

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






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






31. 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.






32. Deoxyribonucleic acid






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






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






35. A fairly typical main sequence star.






36. The capacity to work






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






38. Is the smallest unit of an element that still has the properties of that element.






39. Has the same number of protons and neutrons

42. 1. producer 2. primary consumer 3. secondary consumer 4. tertiary consumer 5. decomposer






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






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






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






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






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






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






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






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