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. An organism that relies primarily on plants for food.






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






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






4. Fertilization of one plant by pollen from a different plant species.






5. A cell with two copies of each chromosome.






6. The phenomenon when refraction of light makes objects appear where they are not.






7. Plants that die after one growing season.






8. A preliminary proposition that can be tested through scientific study.






9. A colorless - odorless gas that is important in the Earth's atmospheric greenhouse effect. Frozen CO2 is dry ice.






10. A protein that aids biochemical reactions.






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






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






13. A layer of tree bramches and other vegetation elevated above ground.






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






15. The study of what causes motion.






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






17. Different versions of a gene in a population.






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






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






20. In plants - a seed includes the embryo.






21. The flow of a charge.






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






23. The loutermost layer of the earth.






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






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

33. The green substance that absorbs light during photosynthesis.






34. 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.






35. A visible group of water or ice particles in the atmosphere.






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






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






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






39. The place on the surface of the Earth immediately above the 'focus' of an earthquake.






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






41. The reproductive parts of flowering plants.






42. Study and interpretation of fossils.






43. The physical - chemical - and biological processes by which rock is broken down into smaller pieces.






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






45. The movement of plates and the interaction across the Earth's surface to form land masses.






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






47. An excess or deficiency of electrons in a body.






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






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






50. The Earth's atmosphere is primarily nitrogen and oxygen. The troposphere extends from the surface to about 10 km.; the stratosphere from 10km to 50 km.; the mesosphere from 50 km. to 80 km.; and the thermosphere is the atmosphere beyond 80 km.
