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






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






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






4. A muscle that pumps to circulate the blood.






5. A solute the denotes protons.






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






7. A substance that can lead to cancer.






8. Evidence of past life.






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






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






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






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






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






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






15. A place whjere frsh water and seawater mix.






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






17. A single DNA molecule - a tightly coiled strand of DNA - condensed into a compact structure.






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






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






20. An identical copy of an organism.






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






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






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






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






25. The process by which gas reverts back to liquid phase.






26. Small proteins that stimulate viral resistance in cells.






27. A cell with two copies of each chromosome.






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






29. The flow of a charge.






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






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






32. A system for transporting nutrients and other essential materials throughout the body.






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






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






35. 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.






36. In the mateamorphosis of insects - the larva becomes a pupa before it becomes an adult.






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






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






39. The reproductive parts of flowering plants.






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






42. Warming of Pacific Ocean seawater along the coast of South America that leads to significant weather changes in the United States.






43. A simple sugar and a product of photosynethesis.






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






45. An kinterstellar cloud of dust and gas.






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






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






48. The larval stage of an aquatic insect.






49. In metamorphosis - the stage between the larva and adult.






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