1 about 79% of the world climate scientists
accept as fact that burning fossil since the
industrial revolution caused a steady increase in
atmospheric CO2 levels and a corresponding rise
in global temperature. Now consider the time
before the industrial revolution. before we began
to burn large amounts of fossil fuels. explain
why naturally fluctuating global temperature
over the last 540 thousand years resulted in
corresponding change in atmospheric CO2
concentration. (CB&M)
2 explain in terms of molecular how
phospholipids are perfectly suited to form
biological members? you may use a diagram to
illustrate this point. (CS&F)
3 in terms of the definition of heat,
describe the properties of a material with a high
thermal conductivity vs. the properties of a
material with a high specific heat capacity. give
an example of each. (THD)
4 rat exterminators often use a pesticide
named warfarin to deal with these pests. although
initially very effective. warfarin appears to be
losing its effectiveness against the rat
population. example why. (note: use what you know
about variation and natural selection. (EVOL).
5 Glycogen is an important molecule found
primarily in the liver, muscles, and brain.
explain how it functions in each of these three
location. Also, what glucose polymer found in
plants is similar to glycogen in structure and
what does it do for the plant?
6 astronomers may learn about distant
galaxies by observing lines in the visible
spectrum given off by burning elements are
slightly closer to red end of the spectrum than
expected. what does this tell her about the
galaxy? explain the effect she is observing?
(S&EM)
7 provide an example of a falsifiable
hypothesis (one that is scientifically testable)
and a non-falsifiable hypothesis (one that is not
scientifically testable). for the falsifiable
hypothesis, briefly describe how you would test
it. For the non-falsifiable hypothesis, explain
why it is not testable. (NS) (do not use religion
as an example)
8 18O and 16O are both isotopes of oxygen.
describe the difference or difference between
them. be specific about the atomic components of
each. would the differences be reflected in as
energy shell diagram? explain why or why not.
(AS)
9 your body has two immunological methods
of protection termed innate and adaptive
immunity. explain the difference between the two.
which method is taken advantage of when creating
vaccines” why does it work?(CB&MS)
10 you begin pushing on a 100-kg golf cart
when it is stationary, and you keep pushing until
it is moving with a velocity of 5/s. if it took
you 50 s to accelerate the golf cart, how much
power did you provide?(EN)
11 a windmill generates electricity without
increasing the concentration of atmospheric
carbon dioxide(CO2). explain how this is
possible. by what mechanism does a windmill
convert mechanical (wind) energy into
electricity? (E&M)
12 a common claim made by intelligent design
(ID) supporters is that features like the eye and
bacterial flagella are “irreducibly complex” and
thus appeared suddenly intact, the product
intelligence, not chance mutation, the driving
force of evolution. therefore, ID should be
taught a scientific alternative to evolution. is
chance mutation the driving force of evolution?
if not, what is the driving force of evolution
13 Gregor Mendel grew over 40,000 pea plant
in the course of his investigation of how traits
were passed down from one generation to another.
what important conclusion did he arrive at, and
what would it have to do with evolution by
natural selection proposed by Darwin in 1859
14 a cliff diver (with a mass of 90
kilograms ) boldly plunges from a rock ledge into
a deep pool, hitting the water in 3 seconds.
(KF/M)
A. what is his velocity when he hits the water?
B. how high is the ledge?
1 5 the atmosphere of Venus is primary
carbon dioxide (96.5%). it has an average
temperature of 735 K, the same temperature
regardless of weather its day or night. Mercury,
a planet that’s closer to the sun, has no
atmosphere. its daily high temperature is 700 K
and nightly low is 100 K (the K scale starts at
absolute 0, so room temperature is 300K ) how is
it possible for Venus to be warmer than Mercury,
and why doesn’t the day/night temperature of
Venus change? explain.
16 you have the opportunity to travel to an area
in Ethiopia that has yielded fossils important to
our understanding of human evolution. you and
friend stumble upon a potentially important find,
a nearly complete skeleton of what appears to be
an early hominid. your friend disagrees, claiming
that it is nothing more than a tree-dwelling
ancestor to a modern chimp. under careful
examination of this fossil, what specific pieces
of fossil evidence may give clues as to which one
of you is likely to be correct (EVOL)
