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.

2. 1. temperature (think movement) 2. pressure






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






4. Has the same number of protons and neutrons






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






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






7. A bond formed when atoms share one or more of their valence electrons.






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






9. Plants response to light






10. As a nebula contracts - the particles collide with colossal force igniting a nuclear reaction and forming a protostar.






11. Phase where spindle grows and which cuts the cell






12. Are affected by the angle from which we view the moon.






13. Spiral disk with several long arms.






14. Matter and energy have the properties of both particles and waves






15. Subatomic particles including: 1. protons 2. neutrons 3. electrons






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






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






18. Calories






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

22. 1. mutualism 2. parasitism 3. commensalism






23. 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.






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