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. Has a pair of chromosomes






2. Describes speed and direction






3. An atom with an imbalanced charge






4. One member of a symbiotic relationship benefit.






5. Is the smallest unit of an element that still has the properties of that element.






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






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






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






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






10. 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.






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






12. 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.






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






14. Are huge clusters of billions of stars






15. 1. evaporation 2. condensation 3. precipitation 4. infiltration 5. runoff






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






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






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






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






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






21. Plants response to light






22. Phase where spindle grows and which cuts the cell






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






24. Is a substance composed of two or more elements






25. 1. mutualism 2. parasitism 3. commensalism






26. Column






27. 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.






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






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






30. Protects and supports the cell






31. Cellular division to create sex cells called haploids.






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






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






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






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






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






37. Pulls apart into two separate cells






38. Stores food and other materials needed by the cell






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






40. A change in position






41. Duplicates genetic material






42. Deoxyribonucleic acid






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






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






45. 1. hair 2. warm - blooded 3. live birth 4. nurses their young






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






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






48. Occurs when heat is transmitted in the form of electromagnetic waves.






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






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