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.

1. The tissue in plants that conducts nutrients.






2. The flow of a charge.






3. A solute that accepts protons.






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






5. 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.






6. 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.






7. 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.






8. A simple sugar and a product of photosynethesis.






9. 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.






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






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






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






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