An algol system is not a classical nova.
Explain why a dwarf nova system must have undergone a common
envelope prior to becoming a dwarf nova. Also explain what happened
during the common envelope phase.
? Explain why entropy in an isolated system must reach its
maximum. Biological system use energy (ultimately from the sun) in
organizing highly ordered organisms, such as humans. Does this mean
that biological system violate the second law of thermodynamics?

1. Explain why the respiratory system and the
renal system have such different time frames in
terms of their physiology for PH response.
2. Regarding the change in the kidneys that characterizes the
renal response to an alkalosis, describe:
a. tubular transport of hydrogen ions:
b. tubular transport of bicarbonate ions:
Explain why the classical theory of light as an electromagnetic
wave (or of electrons as particles) is unable to explain the
following phenomena whereas quantum mechanics is successful.
(1) The turn-on voltage of differently colored LEDs
(2) The existence of transparent conductors
(3) The decrease in frequency of photons scattered off of
atoms
(4) The spectrum of blackbody emission

For each, use 2-3 sentences, 1-2 equations, and a diagram to
provide an explanation that is concise yet precise.
2. Using the Michelson-Morley experiment as an example, explain
why classical mechanics was unable to explain natural
phenomena.
3. Using at least one of Einstein's "thought-experiments",
explain how special relativity addresses how it is possible for
observers in two different inertial reference frames to “disagree”
about time and distance intervals.
Explain why the length of time for the adjustment process to
work in a neo-classical framework lead some economists to believe
fiscal or monetary policy is needed.
. Explain why, according to the classical model, an increase in
government purchases will “crowd out” investment. Suppose that
increased consumer confidence leads to an increase in autonomous
consumption. Would that also crowd out investment, according to the
classical model? Why or why not?

all cells have.
2. Be able to compare and contrast prokaryotic and eukaryotic
cellular characteristics. (including DNA location, cell wall
makeup)
