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






2. A solute that accepts protons.






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






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






5. A cell with two copies of each chromosome.






6. The larval stage of an aquatic insect.






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






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






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






10. An instrument that measures cloud height.






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






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






13. In plants - a seed includes the embryo.






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






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






16. The part of flowering plants that contains seeds.






17. The reproductive parts of flowering plants.






18. Study and interpretation of fossils.






19. Material deposited by a glacier and often marking a glacier's furthest advance.






20. The rate of change of an objects velocity.






21. An kinterstellar cloud of dust and gas.






22. 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.






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






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






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






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






27. A muscle that pumps to circulate the blood.






28. The loutermost layer of the earth.






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






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






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






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






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






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






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






36. The green substance that absorbs light during photosynthesis.






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






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






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






40. An organellein a cell that contains chromosomes.






41. Multicellular organisms whose cells contain organelles.






42. Small proteins that stimulate viral resistance in cells.






43. Reproduction involving only one parent.






44. An instrument to measure wind speed.






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






46. 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.






47. A bundle of neurons - or nerve cells.






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






49. 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.






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