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






3. Force = Mass X Acceleration






4. Phase where spindle grows and which cuts the cell






5. Converts energy from food to energy the cell can use






6. 1. gravity 2. magnetism 3. friction (think of a falling sheet of paper vs. a falling book)






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






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






9. Are huge clusters of billions of stars






10. Angiosperms






11. 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.






12. Has the same number of protons and neutrons






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






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






15. Are caused by the gravitational pull of the Moon and the Sun on the Earth.






16. Column






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






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






19. One member of a symbiotic relationship benefit.






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






21. 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.






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

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






27. Is a homogeneous mixture in which one substance has dissolved into the other - example: salt water






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






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






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






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






32. H2O + CO2 --> CH2O + O2






33. Protects and supports the cell






34. Spiral disk with several long arms.






35. An atom with an imbalanced charge






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






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






38. 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.






39. As temperature increases volume also increases
