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 network of glands and tissues that secrete hormones.






2. A ridge built in water by organisms such as coral.






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






4. 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.






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






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






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






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






9. An instrument that measures cloud height.






10. An identical copy of an organism.






11. 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.






12. Small proteins that stimulate viral resistance in cells.






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






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






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






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






17. A solute the denotes protons.






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






19. The study of what causes motion.






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






21. Compounds that are fats and oils.






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






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






24. 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.






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






26. The fundamental unit of all life. The cell consists of an outer plasma membrane - the cytoplasm - and the genetic material (DNA).






27. A bundle of neurons - or nerve cells.






28. A substance that can lead to cancer.






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






30. The part of flowering plants that contains seeds.






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






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






33. An organism's unique place in the environment.






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






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






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






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






38. The rate of change of an objects velocity.






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






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






41. An organellein a cell that contains chromosomes.






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






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






44. A preliminary proposition that can be tested through scientific study.






45. The larval stage of an aquatic insect.






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






47. Evidence of past life.






48. An almond shaped cloud usually seen on windy days.






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






50. 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.
