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






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






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






4. An organellein a cell that contains chromosomes.






5. The study of what causes motion.






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






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






8. Cell division consisting of prophase - metaphase - anaphase - and telophase - that usually creats in two new nuclei - each with a full set of chromosomes.






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






10. Evidence of past life.






11. A rod - shaped bacteria.






12. A protein that aids biochemical reactions.






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






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






15. Strong upper wind currents in a narrow stream that flow west to east in the United States. Weather patterns are related to the position of the jet stream - which changes often.






16. All the organisms in an area and the environment in which they live.






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






18. A relationship between organisms in which one organism benefits and the other does not die - even though the second organism may be harmed.






19. In plants - a seed includes the embryo.






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






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






22. A system comprised of the brain and spinal cord in vertebrates that process and store information.






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






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






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






26. The reproductive parts of flowering plants.






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






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






29. Compounds that are fats and oils.






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






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






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






33. An organsim that eats meat - which includes animals - fungi - and plants.






34. Small proteins that stimulate viral resistance in cells.






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






36. Atoms of the same chemical element with a different number of neurons but the same number of protons. Isotopes of an element have the same atomic number but may not have the same mass.






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






38. 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.






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






40. Plants that die after one growing season.






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






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






43. An identical copy of an organism.






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






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






46. An instrument to measure wind speed.






47. An instrument that measures cloud height.






48. An organism's unique place in the environment.






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






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