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






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






3. Is the measure of the presence of hydrogen ions in a substance.






4. Has a pair of chromosomes






5. One member of a symbiotic relationship benefit.






6. 1. igneous 2. metamorphic 3. sedimentary






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






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






9. Plants response to gravity






10. Stores food and other materials needed by the cell






11. Spiral disk with several long arms.






12. 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.






13. Energy changes forms but is not created or destroyed.






14. Are a progressive disturbance propagated from point to point (with regularity between points)






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






16. Cellular division to create sex cells called haploids.






17. Is a substance that cannot be separated into simpler substances by chemical means






18. Unless an object is moving in a vacuum - the object causes...






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






20. Caused by the Earth's tilt on its axis. As it revolves arond the Sun - the tilt causes each hemisphere to receive more direct exposure at certain times in its orbit.






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






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






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






24. Plants response to light






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






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






27. Protects and supports the cell






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






29. 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.






30. Grain like organelles that produce proteins






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






32. Occurs when light returns after bouncing off an object.






33. Describes speed and direction






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






35. Anything that has mass and takes up space






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






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






38. A change in position






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






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






41. Control center of the cell






42. Both members of a symbiotic relationship benefit






43. 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.






44. One member benefits - the other is unaffected.






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






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






47. The measure of the kinetic energy in a substance's molecules. Simply - temperature is atomic motion.






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






49. Calories






50. Duplicates genetic material
