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






2. 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.






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






4. A cell that reacts to stimuli and transmits impulses consisting of a body with a nucleus and dendrites to receive and axons to transmit impulses.






5. 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.






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






7. 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.






8. A protein that aids biochemical reactions.






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






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






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






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






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






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






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






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






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






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






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






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






21. An organellein a cell that contains chromosomes.






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






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






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






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






26. A place whjere frsh water and seawater mix.






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






28. Multicellular organisms whose cells contain organelles.






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






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






31. A solute the denotes protons.






32. A simple sugar and a product of photosynethesis.






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






34. 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.






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






36. A substance that can lead to cancer.






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






38. An kinterstellar cloud of dust and gas.






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






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






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






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






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






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






45. The study of what causes motion.






46. The loutermost layer of the earth.






47. Biological molecules that have important roles in energy metabolism and storage as well as the structure of cells and organisms.






48. The green substance that absorbs light during photosynthesis.






49. Evidence of past life.






50. Molten rock flormed in the Earth that may appear on the surface.
