  1. 2. the outer visible portion of the ear that collects and directs sound waves toward the tympanic membrane
  2. 4. mechanical energy that is transmitted by longitudinal pressure waves in a medium (such as air or water)
  3. 5. a graphic representation of the relation of vibration frequency and the minimum sound intensity for hearing
  4. 10. an electronic device usually worn by a person for amplifying sound before it reaches the receptor organs
  5. 11. something which increases risk or susceptibility
  6. 13. a scientifically controlled study of the safety and effectiveness of a therapeutic agent (as a drug or vaccine) using consenting human subjects
  7. 14. the resistance of a group to an attack by a disease to which a large proportion of the members of the group are immune
  8. 15. the essential part of the vertebrae organ of hearing and equilibrium that includes the vestibule, the semicircular canals, and the cochlea
  9. 17. an artificial device to replace or augment a missing or impaired part of the body

  11. 19. a tumor of high malignancy that starts in melanocytes of normal skin or moles and metastasizes rapidly and widely
  12. 20. binds to the ribosomes and blocks key interaction, which shuts off the protein chain; without this protein, the bacteria can no longer grow

  1. 1. the genetic modification of a bacterium by incorporation of free DNA from another ruptured bacterial cell
  2. 3. a small ring of DNA that carries accessory genes separate from those of the bacterial chromosome
  3. 6. a display of the chromosome pairs of a cell arranged by size and shape
  4. 7. the genetic makeup of an organism
  5. 8. a harmless variant of a pathogen that stimulates a host's immune system to mount defense against the pathogen
  6. 9. the collection, classification, storage, and analysis of biochemical and biological information using computers especially as applied in molecular genetics and genomics
  7. 12. inhibit the use of metabolite antimetabolite, which is used for normal metabolism; this substrate is needed for folic acid biosynthesis
