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.

8. Angiosperms






9. The quantity of substance






10. Refers to the vast periods of time over which the Earth changes.






11. Describes speed and direction

19. Are huge clusters of billions of stars






20. The point around which a lever rotates






21. Control center of the cell






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






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






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






25. 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.






26. Duplicates genetic material






27. Stamen






28. Stores food and other materials needed by the cell






29. Phase where spindle grows and which cuts the cell






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

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






45. Causes beneficial traits to be propagated and detrimental traits to be eliminated.






46. 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.
