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 protein that aids biochemical reactions.






2. A preliminary proposition that can be tested through scientific study.






3. A temperature scale in which water freezes at 0 degrees and boils at 100 degrees.






4. A relationship between organisms in which one organism benefits and the other does not die - even though the second organism may be harmed.






5. Light refracted through raindrops to form colors of a spectrum from red to blue.






6. A single DNA molecule - a tightly coiled strand of DNA - condensed into a compact structure.






7. Reproductive haploid cells that combine to creat a zygote.






8. An instrument to measure wind speed.






9. The movement up in the atmosphere of heated moisture. Thunderstorms are often caused by convection.






10. The framework for the attatchment of skeletal muscles in vertebrates that also protect vital organs.






11. The process by which gas changes directly to the solid phase.






12. The part of Earth located between the crust and the core.






13. That part of the body cavity between the mouth and the anus including in most animals the mouth - the pharynx - esophagus - stomach - intestine - and the anus.






14. A dry - north wind in late spring - summer - and early fall in north and central California.






15. Strong upper wind currents in a narrow stream that flow west to east in the United States. Weather patterns are related to the position of the jet stream - which changes often.






16. A muscle that pumps to circulate the blood.






17. A ridge built in water by organisms such as coral.






18. A temperature scale in which 1 degrees Kelvin equals 1 degree Celsius. 0 degree Kelvin is about -273 degree Celsius. Kelvin is called absolute zero because there is no movement of molecules.






19. A place whjere frsh water and seawater mix.






20. The study of what causes motion.






21. A hormone needed to transpost glucose to cells.






22. The tissues aquatic animals use to breath in water.






23. Different versions of a gene in a population.






24. The process by which seeds develop into seedlings.

26. The study of the interactions of organisms with their environment and with each other.






27. An organsim that eats meat - which includes animals - fungi - and plants.






28. The combined cooling effect of wind and temperature. Higher wind chills indicate that a body will cool more quickly to the air temperature.






29. A process through which organisms make nutrients available to cells.






30. All the organisms in an area and the environment in which they live.






31. The level of plant and animal between the species and the family.






32. Rings that show how many years a tree has been growing. The thickness of the rings may reveal other information about climatic conditions.






33. A term used to describe the coiling strands of DNA molecule that resembles a spiral staircase.






34. A rod - shaped bacteria.






35. An identical copy of an organism.






36. An organism that relies primarily on plants for food.






37. The physical - chemical - and biological processes by which rock is broken down into smaller pieces.






38. In metamorphosis - the stage between the larva and adult.






39. In the mateamorphosis of insects - the larva becomes a pupa before it becomes an adult.






40. The reproductive mechanism of prokaryotes.






41. A simple sugar and a product of photosynethesis.






42. A cancer treatment that includes chemicals toxic to mailgnant cells.






43. The process by which gas reverts back to liquid phase.






44. An organism's unique place in the environment.
