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.

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






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






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






19. 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.






20. An organellein a cell that contains chromosomes.






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






22. The reproductive mechanism of prokaryotes.






23. Reproductive haploid cells that combine to creat a zygote.






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






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






26. 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.






27. `An important class of plant hormones associated with growth patterns.






28. The larval stage of an aquatic insect.
