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. A protein that aids biochemical reactions.






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






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






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






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






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






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






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






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






10. A temperature scale in which water freezes at 0 degrees and boils at 100 degrees.






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






12. An organellein a cell that contains chromosomes.






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






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






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






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






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






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






19. The reproductive mechanism of prokaryotes.






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






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






22. `An important class of plant hormones associated with growth patterns.






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






24. A simple sugar and a product of photosynethesis.






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






26. Reproduction involving only one parent.






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






28. A muscle that pumps to circulate the blood.






29. The study of what causes motion.






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






31. 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.






32. 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.






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






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






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






36. A cell with two copies of each chromosome.






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






38. An instrument that measures cloud height.






39. A rod - shaped bacteria.






40. The reproductive parts of flowering plants.






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






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






43. Study and interpretation of fossils.






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






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






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






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






48. The green substance that absorbs light during photosynthesis.






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






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