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






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






3. A muscle that pumps to circulate the blood.






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






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






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






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






8. 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.






9. 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.






10. A substance that can lead to cancer.






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






12. The reproductive parts of flowering plants.






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






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






15. Small proteins that stimulate viral resistance in cells.






16. An kinterstellar cloud of dust and gas.






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






18. The process in which a diploid cell divides to form haploid cells.






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






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






21. The reproductive mechanism of prokaryotes.






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






23. 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.






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






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






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






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






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






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






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






31. Reproduction involving only one parent.






32. 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.






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






34. A place whjere frsh water and seawater mix.






35. The loutermost layer of the earth.






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






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






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






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






40. 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.






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






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






43. A rod - shaped bacteria.






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






45. Different versions of a gene in a population.






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






47. A solute the denotes protons.






48. The process by which seeds develop into seedlings.






49. A way to date organic substances based on the carbon -14 remaining.






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