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






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






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






4. Stores food and other materials needed by 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. Are huge clusters of billions of stars






8. 1. egg 2. tadpole (breathes water) 3. metamorphosis 4. adult frog (breathes air)






9. One member of a symbiotic relationship benefit.






10. 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.






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






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


13. Cellular division to create sex cells called haploids.






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






15. Is a change in velocity






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






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






18. Phase where spindle grows and which cuts the cell






19. An ion






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






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






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






23. Both members of a symbiotic relationship benefit






24. 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.






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






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






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

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






47. Caused by the Earth's tilt on its axis. As it revolves arond the Sun - the tilt causes each hemisphere to receive more direct exposure at certain times in its orbit.






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






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






50. Anything that has mass and takes up space
