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






2. The flow of a charge.






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






4. The rate of change of an objects velocity.






5. A substance that can lead to cancer.






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






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






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






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






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






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






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






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

16. The part of the gut that connects the pharynx and stomach.






17. Small proteins that stimulate viral resistance in cells.






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






19. This primary component of chromosomes carries an organisms genetic code.






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






21. 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.

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






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






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

45. Study and interpretation of fossils.






46. A bundle of neurons - or nerve cells.






47. A hormone needed to transpost glucose to cells.






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






49. A warm - dry wind on the eastern side of the Rocky Mountains.






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