  1. qualitative observation
    observable qualities such as texture, smell, color, shape, sounds
  2. quantitative observation
    numerical measurements of objects or quantities of objects
  3. microscope micrometer scale:
    scanning lens:
    low power lens:
    high power lens:
    • scanning lens: 25 um
    • low power lens: 10 um
    • high power lens: 2.5 um
  4. metabolism
    • the ability to use energy
    • includes all of the chemical reactions in the body
  5. homeostasis
    the maintenance of a constant internal environment, despite changes in an organism's external environment
  6. responsiveness
    the ability of living things to respond to stimuli
  7. asexual reproduction
    production of new body cells to form the new individual, resulting in a genetically identical copy of the original organism
  8. sexual reproduction
    production of genetically variable sex cells called gametes which, when combined, will result in new genetic combination in the offspring
  9. adaptation
    a characteristic of a species that allows survival
  10. 3 types of adaptation:
    • physical -- body form or covering
    • physiological -- involves internal body chemistry or timing of life processes
    • behavioral -- how the animal reacts to external stimuli that aids their survival or reproductive success
  11. what color stripe does each objective lens have?
    • scanning - red
    • low power - yellow
    • high power - blue
  12. what are the powers of the ocular lens and the three objective lenses?
    • ocular - 10x
    • scanning - 4x
    • low power - 10x
    • high power - 40x
