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






2. An organellein a cell that contains chromosomes.






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






4. A process through which organisms make nutrients available to cells.






5. In plants - a seed includes the embryo.






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






7. The reproductive mechanism of prokaryotes.






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






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






10. A place whjere frsh water and seawater mix.






11. The tissue in plants that conducts nutrients.






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






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






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






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






16. 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.






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