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






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






3. The fundamental unit of all life. The cell consists of an outer plasma membrane - the cytoplasm - and the genetic material (DNA).






4. The study of what causes motion.






5. 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.

7. Compounds that are fats and oils.






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

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






11. The process by which seeds develop into seedlings.

15. The reproductive mechanism of prokaryotes.






16. The part of Earth located between the crust and the core.






17. A protein that aids biochemical reactions.






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






19. 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.






20. A bundle of neurons - or nerve cells.






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

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






40. A place whjere frsh water and seawater mix.






41. The combined cooling effect of wind and temperature. Higher wind chills indicate that a body will cool more quickly to the air temperature.






42. Reproduction involving only one parent.






43. Light refracted through raindrops to form colors of a spectrum from red to blue.






44. An instrument that measures cloud height.






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

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






48. An instrument that uses air pressure to record height - such as the height of a plane.






49. 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.






50. This primary component of chromosomes carries an organisms genetic code.
