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






2. 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.






3. 1. Law of Inertia 2. Law of Acceleration 3. Law of Reciprocal Actions

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






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






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






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






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






11. For every action there is an equal and opposite reaction.






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






13. 1. mutualism 2. parasitism 3. commensalism






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






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






16. 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.






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

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






21. The Moon and the Sun are on opposite sides of the Earth.






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






23. Phase where spindle grows and which cuts the cell






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






25. Grain like organelles that produce proteins






26. Protects and supports the cell






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






28. Plants response to gravity






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






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






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






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






33. Control center of the cell






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






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






36. Cellular division to create sex cells called haploids.






37. The quantity of substance
