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






2. A muscle that pumps to circulate the blood.






3. A bundle of neurons - or nerve cells.






4. The process by which gas changes directly to the solid phase.






5. The flow of a charge.






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

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






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






14. A cancer treatment that includes chemicals toxic to mailgnant cells.






15. A cell with one set of chromosomes - which is half the regular (diploid) number.






16. A term used to describe the coiling strands of DNA molecule that resembles a spiral staircase.






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






18. The process by which seeds develop into seedlings.

20. A cell with two copies of each chromosome.






21. That part of the body cavity between the mouth and the anus including in most animals the mouth - the pharynx - esophagus - stomach - intestine - and the anus.






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






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

41. The digestive tract between the stomach and anus where most nutrients are absorbed.






42. A hormone needed to transpost glucose to cells.






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