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






2. A rod - shaped bacteria.






3. Plants that live through more than one growing season.






4. The rate of change of an objects velocity.






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






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






7. An identical copy of an organism.






8. When the sun is highest in the sky and directly above the Tropic of Cancer 23 1/2 degrees North Latitude. This date usually falls on June 22.






9. The loutermost layer of the earth.






10. The green substance that absorbs light during photosynthesis.






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






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






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






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






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






16. 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.






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






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






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






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






21. A simple sugar and a product of photosynethesis.






22. Plants that die after one growing season.






23. A hormone needed to transpost glucose to cells.






24. The movement and collision of gas molecules in the atmosphere that can form into high or low pressure areas.






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






26. Multicellular organisms whose cells contain organelles.






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






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






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






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






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






32. The reproductive mechanism of prokaryotes.






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






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






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






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






37. The tissues aquatic animals use to breath in water.






38. An instrument that measures cloud height.






39. A muscle that pumps to circulate the blood.






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






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






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






43. One nautical mile per hour or about 1.15 miles per hour.






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






45. 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.






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






47. A cell with two copies of each chromosome.






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






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






50. An organellein a cell that contains chromosomes.
