CSET Science Vocab 2

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.

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






5. A rod - shaped bacteria.






6. The flow of a charge.






7. The larval stage of an aquatic insect.






8. A relationship between disimilar organisms that is adventageous to one and doesn't affect the other.






9. A tissue in the uterus through which nutrients pass from the mother to the fetus.






10. Movement of pollen to a plant egg cell - often b y wind - bees - or other animals.






11. This primary component of chromosomes carries an organisms genetic code.






12. Small proteins that stimulate viral resistance in cells.






13. Floating aquatic plants (phytoplankton) and animals (zooplankton).






14. A place whjere frsh water and seawater mix.






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






16. A system comprised of the brain and spinal cord in vertebrates that process and store information.






17. Soil beneath the earth's surface that stays frozen throughout the year.






18. A protein that aids biochemical reactions.






19. Light emission from the upper atmosphere that appear in many shapes and colors.






20. An instrument to measure wind speed.






21. 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.






22. Material deposited by a glacier and often marking a glacier's furthest advance.






23. An excess or deficiency of electrons in a body.






24. The fundamental unit of all life. The cell consists of an outer plasma membrane - the cytoplasm - and the genetic material (DNA).






25. An kinterstellar cloud of dust and gas.






26. A warm - dry wind on the eastern side of the Rocky Mountains.






27. A substance that can lead to cancer.






28. A dark cloud - but not a thundercloud - the frequently produces rain.






29. The Earth's atmosphere is primarily nitrogen and oxygen. The troposphere extends from the surface to about 10 km.; the stratosphere from 10km to 50 km.; the mesosphere from 50 km. to 80 km.; and the thermosphere is the atmosphere beyond 80 km.






30. The movement and collision of gas molecules in the atmosphere that can form into high or low pressure areas.






31. An identical copy of an organism.






32. Plants that die after one growing season.






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






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






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






36. 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.

38. The part of flowering plants that contains seeds.






39. In plants - a seed includes the embryo.






40. The movement of plates and the interaction across the Earth's surface to form land masses.






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






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






43. An instrument that measures cloud height.






44. The process by which seeds develop into seedlings.






45. Precipitation that evaporates before it reaches the Earth's surface.






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






47. An instrument that uses air pressure to record height - such as the height of a plane.






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






49. An organellein a cell that contains chromosomes.






50. Study and interpretation of fossils.
