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. The reproductive mechanism of prokaryotes.






2. An organellein a cell that contains chromosomes.






3. Precipitation that evaporates before it reaches the Earth's surface.






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






5. A tissue in the uterus through which nutrients pass from the mother to the fetus.






6. The study of what causes motion.






7. A substance that can lead to cancer.






8. In the United States - the part of the western mountains that seperates water flowing toward opposite sides of the country.






9. Long term patterns of temperature - humidity and amount of sunshine.






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






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






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






13. The movement up in the atmosphere of heated moisture. Thunderstorms are often caused by convection.






14. The green substance that absorbs light during photosynthesis.






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






16. The loutermost layer of the earth.






17. 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.






18. An kinterstellar cloud of dust and gas.






19. Material deposited by a glacier and often marking a glacier's furthest advance.






20. An identical copy of an organism.






21. The process by which seeds develop into seedlings.






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






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






24. A rod - shaped bacteria.






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






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






27. A bundle of neurons - or nerve cells.






28. An organism that relies primarily on plants for food.






29. Molten rock flormed in the Earth that may appear on the surface.






30. A solute that accepts protons.






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






32. A way to date organic substances based on the carbon -14 remaining.






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






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






35. The process in which a diploid cell divides to form haploid cells.






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






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






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






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






40. 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.






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






42. A cell with two copies of each chromosome.






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






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






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






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






47. In most Amphibians - a process in which larve goes through significant changes - perhaps including a pupa stage - before becoming an adult.






48. A disease related to lower levels of insulin.






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






50. The tissue in plants that conducts nutrients.
