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. 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.






2. Stamen






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






4. An ion






5. Asserts that organisms have changed over time to adapt to the unique and varied demands of their changing environments.


6. The capacity to work






7. Material inside the cell membrane -- not including the nucleus






8. 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.






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






10. 1. producer 2. primary consumer 3. secondary consumer 4. tertiary consumer 5. decomposer






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






12. A change in position






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






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






15. Phase where spindle grows and which cuts the cell






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






17. Is the particular wavelength of light we observe that is not absorbed by an object.






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






19. Calories






20. Has a pair of chromosomes






21. Column






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






23. Causes salt to move across a permeable membrane from an area of greater salinity to an area of lesser salinity.






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






25. Is a change in velocity






26. 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.






27. Duplicates genetic material






28. 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.






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






30. 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.






31. When the Moon or the Sun are pulling at perpendicular angles we get less extreme tides.






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






33. Plants response to light






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






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






36. One member of a symbiotic relationship benefit.






37. 1. positive charge 2. located in nucleus 3. mass is 1 AMU






38. Forms the key building block at an atomic level.






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






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






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






42. Within compounds - the various atoms making up molecules are held together by...






43. The time required by half the atoms of a particular substance to disintegrate






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






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






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






47. The amount of matter that makes up an atom. You can estimate an atom's atomic mass by adding up the total number of protons and neutrons.






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






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






50. 1. puzzle piece argument 2. sea floor spreading 3. fossil records
