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 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.






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






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






4. A hormone needed to transpost glucose to cells.






5. Compounds that are fats and oils.






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






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






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






9. An kinterstellar cloud of dust and gas.






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






11. A cell that reacts to stimuli and transmits impulses consisting of a body with a nucleus and dendrites to receive and axons to transmit impulses.






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






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






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






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






16. Evidence of past life.






17. The rate of change of an objects velocity.






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






19. 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.






20. A simple sugar and a product of photosynethesis.






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






22. Plants that die after one growing season.






23. The study of what causes motion.






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






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






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






27. 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.






28. Small proteins that stimulate viral resistance in cells.






29. Multicellular organisms whose cells contain organelles.






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






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






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






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






34. The loutermost layer of the earth.






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






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






37. 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.






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






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






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






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






42. The part of flowering plants that contains seeds.






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






44. A group of plants that produce seeds enclosed within an ovary - which mat mature into a fruit.






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






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






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






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






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






50. Different versions of a gene in a population.
