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






2. Calories






3. Occur because the shadow of the Earth or the Moon is cast onto the other body.






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






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






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






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






8. Grain like organelles that produce proteins






9. An atom with an imbalanced charge






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






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






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






13. 1. convergent 2. divergent 3. transform






14. Stored energy






15. The Moon and the Sun are on opposite sides of the Earth.






16. 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.

21. 1. by row 2. atomic number and mass increase as you move left to right and top to bottom






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






23. 1. egg 2. larvae 3. pupae/crysalis 4. imago/adult butterfly






24. 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.






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

31. Is a substance composed of two or more elements






32. Angiosperms






33. One member of a symbiotic relationship benefit.






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

38. Stamen






39. The capacity to work






40. Is a change in velocity






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






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






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






44. Duplicates genetic material






45. 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.






46. 1. Law of Inertia 2. Law of Acceleration 3. Law of Reciprocal Actions
