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.
1. The green substance that absorbs light during photosynthesis.






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






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






4. The part of flowering plants that contains seeds.






5. The network of glands and tissues that secrete hormones.






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






7. Small proteins that stimulate viral resistance in cells.






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






9. 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.






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






11. Multicellular organisms whose cells contain organelles.






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






13. Evidence of past life.






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






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






16. A colorless - odorless gas that is important in the Earth's atmospheric greenhouse effect. Frozen CO2 is dry ice.






17. 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.






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






19. 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.






20. A hormone needed to transpost glucose to cells.






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






22. Atoms of the same chemical element with a different number of neurons but the same number of protons. Isotopes of an element have the same atomic number but may not have the same mass.






23. The reproductive parts of flowering plants.






24. A rod - shaped bacteria.






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






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






27. A system for transporting nutrients and other essential materials throughout the body.






28. When the sun is directly over the equator. This date usually occurs on March 20.






29. Fertilization of one plant by pollen from a different plant species.






30. In plants - a seed includes the embryo.






31. A loud nise caused by a shock wave when an object exceeds the speed of sound.






32. An identical copy of an organism.






33. A visible group of water or ice particles in the atmosphere.






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






35. A place whjere frsh water and seawater mix.






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






37. A way to date organic substances based on the carbon -14 remaining.






38. Plants that die after one growing season.






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






40. An organellein a cell that contains chromosomes.






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






42. A protein that aids biochemical reactions.






43. A disease related to lower levels of insulin.






44. An instrument that measures cloud height.






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






46. A mammal whose young crawl into it's mothers pouch to complete development.






47. `An important class of plant hormones associated with growth patterns.






48. The part of the gut that connects the pharynx and stomach.






49. One nautical mile per hour or about 1.15 miles per hour.






50. Cell division consisting of prophase - metaphase - anaphase - and telophase - that usually creats in two new nuclei - each with a full set of chromosomes.
