  1. Which of the following about prostaglandins is FALSE?

    Promote inflammation
    Can only constrict blood vessels
    Are made in the renal medulla
    Lead to pain & fever
    Can only constrict blood vessels

    Prostaglandins can constrict AND dialate vessels
  2. What are the differences between

    Endocrine
    Paracrine
    Autocrine
    Endocrine hormones are created at a descrite site and sent to act upon another

    Paracrine signalling is when the target cell is near the signal releasing cell (para = near)

    Autocrine signalling is when the target cell is itself

    Prostaglandins are either paracrine or autocrine signalling
  3. What is Litmus Paper used for?

  6. What is the the Ideal Gas Law?
    What is its formula?
    • The ideal gas law is the equation of state of a hypothetical ideal gas.
    • It is a good approximation to the behavior of many gases under many conditions
    • It has several limitations
    • PV=nRT or PV=knT
  7. What is Archimedes Principle?
    The object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object

    Any floating object displaces its own weight of fluid
  8. What is Charle's Law?
    • aka "The Law of Volumes"
    • Gas expands as its temperature increases
  9. What is Boyle's Law?
    aka Boyle-Mariotte Law

    • A fixed amount of an ideal gas kept at a fixed temperature
    • P [pressure] and V [volume] are inversely proportional
    • while one doubles, the other halves

    pV= k

    k is a constant value representative of the pressure and volume of the system
  10. What is Anderson's Rule / Anderson's Principle?
    When constructing an energy band diagram, the vacuum levels of the two semiconductors on either side of the heterojunction should be aligned (at the same energy)
  11. In chemistry, ________ is the tendency for a substance to vaporize.
    Volatilty
  12. What does it mean if a liquid is the following?

    Viscous
    Volatile
    Evaporative
    Transient
    • Viscous / Viscosity
    • - The resistence of a liquid that is being deformed (harder or easy to pour)

    • Volatile / Volatility
    • - Tendency for a substance to vaporize

    • Evaporative / Evaporation
    • - Vaporization of a liquid that occurs only on the surface
    • - NOT the same as boiling which occurs on the entire mass of the liquid

    • Transient
    • - A nonperiodic signal of short duration
    • - A decaying signal, wave, or oscillation
    • - Has nothing to do with liquids
  13. Albert Michelson is...
    • First American to win a Nobel Prize in science
    • Measuring speed of light
  14. A Fundamental Wave / Frequency is...
    • Abbreviated as fo
    • The lowest frequency of a periodic waveform
    • Lowest frequency sinusoidal in the sum.
  15. Overtones are...
    Any frequency higher than the fundamental frequency of a sound
  16. High frequency sound waves are known as__________
    Overtones
  17. Consonance vs Dissonance Waves
    • Consonance
    • - Considered stable (at rest)
    • - Combo of notes that sound pleasant when played at the same time

    • Dissonance
    • - Considered unstable (or temporary, transitional)
    • - Combo of notes that sound harsh or unpleasant
  18. What is a Lewis Acid? A Lewis Base?
    Usually defined within terms of a chemical reaction

    • Lewis Acid is an electron pair acceptor
    • Example: H+ is a Lewis Acid because it can accept a lone pair completing its stable form

    • Lewis Base is an electron pair donator
    • Examples: OH− & NH3
  19. NaCL is considered a _______ bond
    Ionic
  20. Forces can be indicated on graph paper by the use of ______
