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






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






3. Has the same number of protons and neutrons






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






5. Column






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






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






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






9. Duplicates genetic material






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






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






12. Cellular division to create sex cells called haploids.






13. 1. mutualism 2. parasitism 3. commensalism






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






15. Stored energy






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






17. 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.






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






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






20. It spreads the work over a greater distance along the planes of the wedge.






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






22. Is a change in velocity






23. Has a pair of chromosomes






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






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






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

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






29. Asserts that organisms have changed over time to adapt to the unique and varied demands of their changing environments.


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






31. Both members of a symbiotic relationship benefit






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






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






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