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.

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






3. Floating aquatic plants (phytoplankton) and animals (zooplankton).






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






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






6. The movement and collision of gas molecules in the atmosphere that can form into high or low pressure areas.

12. The portion of the Earth from beneath the mantle to the Earth's center.






13. A solute the denotes protons.






14. A malignant tumor - which forms in the skin and outside of internal organs.






15. Biological molecules that have important roles in energy metabolism and storage as well as the structure of cells and organisms.






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






17. Rings that show how many years a tree has been growing. The thickness of the rings may reveal other information about climatic conditions.

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






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






48. 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.






49. The tissue in plants that conducts nutrients.






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