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 reproductive parts of flowering plants.






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

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






5. A hormone needed to transpost glucose to cells.

7. The loutermost layer of the earth.






8. A muscle that pumps to circulate the blood.






9. Calender days when the day and night are the same length.






10. 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.






11. 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.






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

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






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






19. A dry - north wind in late spring - summer - and early fall in north and central California.






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