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






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






3. Plants response to gravity

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






14. 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.






15. 1. convergent 2. divergent 3. transform






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






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

19. 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.






20. Can occur by chemical means such as acid rain or physical means - such as wind - rain and ice.






21. Thin - flexible barrier around a cell; regulates what enters and leaves the cell






22. Column

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






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






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






29. 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.






30. Energy in motion






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