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 tissues aquatic animals use to breath in water.






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






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






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






5. The digestive tract between the stomach and anus where most nutrients are absorbed.






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






7. Multicellular organisms whose cells contain organelles.






8. 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.






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. Compounds that are fats and oils.






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






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






13. When the sun is highest in the sky and directly above the Tropic of Cancer 23 1/2 degrees North Latitude. This date usually falls on June 22.






14. An kinterstellar cloud of dust and gas.






15. The loutermost layer of the earth.






16. An identical copy of an organism.






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






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






19. An almond shaped cloud usually seen on windy days.






20. A layer of tree bramches and other vegetation elevated above ground.






21. The process by which seeds develop into seedlings.






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






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






24. 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.






25. A cell with one set of chromosomes - which is half the regular (diploid) number.






26. The flow of a charge.






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






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 hormone needed to transpost glucose to cells.






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






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






32. Evidence of past life.






33. Plants that die after one growing season.






34. The green substance that absorbs light during photosynthesis.






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






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






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






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






39. Long term patterns of temperature - humidity and amount of sunshine.






40. In most Amphibians - a process in which larve goes through significant changes - perhaps including a pupa stage - before becoming an adult.






41. The rate of change of an objects velocity.






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






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






44. A protein that aids biochemical reactions.






45. Small proteins that stimulate viral resistance in cells.






46. Study and interpretation of fossils.






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






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






49. A substance that can lead to cancer.






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