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






2. A fairly typical main sequence star.






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






4. One member benefits - the other is unaffected.






5. Grain like organelles that produce proteins






6. A change in position






7. Has a pair of chromosomes






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






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






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






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






12. 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.






13. Protects and supports the cell






14. Duplicates genetic material






15. Angiosperms






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






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






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






19. 1. solid 2. liquid 3. gas






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






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






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






23. The point around which a lever rotates






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






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






26. 1. igneous 2. metamorphic 3. sedimentary






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






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






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






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






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






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






33. Cell begins to split






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






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






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






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






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






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






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






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






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






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






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






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






47. 1. the more massive either or both bodies are - the greater the gravitational force between them. 2. the further apart two bodies are - the lesser the gravitational force between them.






48. An ion






49. Are huge clusters of billions of stars






50. Cellular division to create sex cells called haploids.
