CSET Science Vocab 2

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.

3. The network of glands and tissues that secrete hormones.






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






5. A muscle that pumps to circulate the blood.






6. A bundle of neurons - or nerve cells.






7. A system comprised of the brain and spinal cord in vertebrates that process and store information.






8. When the sun is directly over the equator. This date usually occurs on March 20.






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






10. A cell with two copies of each chromosome.






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






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






13. The study of the interactions of organisms with their environment and with each other.






14. The framework for the attatchment of skeletal muscles in vertebrates that also protect vital organs.






15. A ridge built in water by organisms such as coral.






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






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






18. Light emission from the upper atmosphere that appear in many shapes and colors.






19. The study of the patterns and mechanisms of the transmission of inherited traits from one generation to another.






20. The stage of cellular divisions that develops from a zygote.






21. A protein that aids biochemical reactions.






22. The tissue in plants that conducts nutrients.






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






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






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