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






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






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






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






5. The tissue in plants that conducts nutrients.






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






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






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






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






10. A cell with two copies of each chromosome.






11. Long term patterns of temperature - humidity and amount of sunshine.






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






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






14. The green substance that absorbs light during photosynthesis.






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






16. The reproductive parts of flowering plants.






17. Different versions of a gene in a population.






18. An organellein a cell that contains chromosomes.






19. 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.






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






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






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






23. 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.






24. Multicellular organisms whose cells contain organelles.






25. 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.






26. An instrument that measures cloud height.






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






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






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






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






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






32. A muscle that pumps to circulate the blood.






33. An instrument to measure wind speed.






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






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






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






37. A dry - north wind in late spring - summer - and early fall in north and central California.






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






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






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






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






42. An kinterstellar cloud of dust and gas.






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






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






45. 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.






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






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






48. The process by which seeds develop into seedlings.






49. Evidence of past life.






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