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 tissue in plants that conducts nutrients.






2. Plants that die after one growing season.






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






4. The study of what causes motion.






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






6. The place on the surface of the Earth immediately above the 'focus' of an earthquake.






7. A muscle that pumps to circulate the blood.






8. The portion of the Earth from beneath the mantle to the Earth's center.






9. 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.






10. An identical copy of an organism.






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






12. The green substance that absorbs light during photosynthesis.






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






14. In the United States - the part of the western mountains that seperates water flowing toward opposite sides of the country.






15. Reproduction involving only one parent.






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






17. Warming of Pacific Ocean seawater along the coast of South America that leads to significant weather changes in the United States.






18. The reproductive mechanism of prokaryotes.






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






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






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






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






23. A bundle of neurons - or nerve cells.






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






25. A substance that can lead to cancer.






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






27. 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.






28. A rod - shaped bacteria.






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






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






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






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






33. The loutermost layer of the earth.






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






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






36. A level of plant and animal classification between class and kingdom.






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






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






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






40. Different versions of a gene in a population.






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






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






43. The phenomenon when refraction of light makes objects appear where they are not.






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






45. The reproductive parts of flowering plants.






46. Fluid that circulates throughout the body of an animal - distributing nutrients - and usually oxygen.






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






48. The study of the patterns and mechanisms of the transmission of inherited traits from one generation to another.






49. Study and interpretation of fossils.






50. Evidence of past life.
