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. convergent 2. divergent 3. transform






2. Is a change in velocity






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






4. 1. kingdom 2. phylum 3. class 4. order 5. family 6. genus 7. species






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






6. Has a pair of chromosomes






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






8. The capacity to work






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






10. Organelle found in cells of plants and some other organisms that captures the energy from sunlight and convert it into chemical energy






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






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






13. Converts energy from food to energy the cell can use






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






15. A fairly typical main sequence star.






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






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






18. Occurs when cooler portions of a liquid or gas flow in to take the place of hotter - rising portions.






19. 1. negative charge 2. located in the nucleus 3. mass is about 1/1836th of an AMU






20. Control center of the cell






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






22. Is a change from one state to another without a change in chemical composition.






23. 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.






24. A group of subjects upon which a hypothesis is tested.






25. Is a method of separating ions within a substance by passing electrical current through the substance






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






27. 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.






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






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






30. Require a medium and travel much slower than light.






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






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






33. 1. State the problem. 2. Form a hypothesis. 3. Observe and experiment. 4. Interpret the data. 5. Draw conclusions.






34. 1. homeostasis 2. organization 3. metabolism 4. growth 5. adaptation 6. response to stimuli 7. reproduction

38. Are huge clusters of billions of stars






39. Is a substance composed of two or more elements






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






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






42. 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.






43. Phase where spindle grows and which cuts the cell






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






45. The point around which a lever rotates






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