    inference
  16. Why do organisms share similar classification levels?
    The more classification levels they share the more characteristics they have in common.

    • line graph
    • pie graph
    • bar graph
    • charts
    • data tables
    • diagrams
    • pictures
    • making models

    True
  19. What important ingredients do scientists include when making a graph to share with others to?
    capitalized/centered titles, 2 subtitles, zero on graph, increments to fit data, plot or connect points and color in data
  20. Why are viruses great messengers of genetic information?
    Because of their ability to enter cells
  21. Looking out your window you notice your neighbor's dog sitting in the back yard.  Is that an inference or an observation?
    observation
  22. What is a change in an organism's surroundings that causes the organism to react?
    stimulus
  23. What level of classification is where organisms mate with like or similar organisms?
    species
  24. What is an action or change in behavior that occurs as a result of a stimulus?

  25. What do scientists call getting bigger?
    growth
  26. What is the process of change that occurs during an organism's life to produce a more complex organism?
    development
  27. What are 4 basic needs of living things?
    • 1. water
    • 2. energy
    • 3. living space
    • 4. stable internal conditions
  28. Why do scientists put things into groups in an organized way?
    so the organisms are easier to study
  29. What are 6 characteristics that living things share?
    • 1.cellular organization
    • 2.contain similar chemicals
    • 3.use energy
    • 4.grow and develop
    • 5.respond to their surroundings
    • 6.reproduce
  30. What are the names of the 3 domains?
    • Bacteria
    • Archaea
    • Eukarya
  31. Viruses need energy to __________.
    multiply
  32. How do scientists place organisms into kingdoms?
    • 1. Based on their types of cells,
    • 2. their ability to make food 
    • 3. and the number of cells in their bodies
  33. What are the 4 kingdoms that living things are placed in?
    • Protists
    • Fungi
    • Plants
    • Animals
  34. What do scientists call organisms that CAN make their own food?
    autotrophs (plants)
  35. Autotrophs use the ____ 's   ______ to help make their own food to use as an energy source to carry out life's functions.
    sun's energy
  36. What is an animal called that can NOT make its own food?  It uses the sun's energy in an indirect way.  They eat stored energy in autotrophs or heterotrophs.
    heterotroph
  37. What are characteristics that plants have in common with other plants?
    • multicellular eukaryotes
    • make their own food
    • life exists on earth because of them
  38. Why are bacteria called decomposers? Why are bacteria so important on earth?

  42. Why do scientists now classify organisms into more than just the plant and animal kingdom?
    (The domain level was added for this reason)
    The use of the modern technology, especially use of a high powered microscope, led to the discovery of many new organisms and the identification of differences among cells.
