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. 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.






2. Plants response to gravity






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






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






5. One member of a symbiotic relationship benefit.






6. 1. inner core 2. outer core 3. mantle 4. crust






7. An atom that has a different number of neutrons than its normal amount.






8. 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.






9. Protects and supports the cell






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






11. Plants response to light






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






13. 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.






14. C14 dating only works on organisms that died less than _____ years ago.






15. Calories






16. Is a change in velocity






17. The number of protons a particular type of atom has. The atomic number defines the type of element.






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






19. Control center of the cell






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






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






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






23. That space and time are relative - not absolute concepts






24. 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.






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






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






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






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






29. Cellular division to create sex cells called haploids.






30. A change in position






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






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






33. 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.






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






35. Angiosperms
