Based on what you know about life and elements, select
the most likely explanation of how that sunflowers can tolerate heavy metals at concentrations
that kill most organisms.
A) Sunflowers have evolved the ability convert these heavy metals (like lead) to transitional
metals (like cobalt) by removing protons from the atoms of the heavy metal.
B) The cells of the sunflower store the heavy metals in compartments that are not accessible to
other parts of the cell and plant.
C) Sunflowers have evolved the ability to remove neutrons from the atoms of these heavy
metals,
which destabilize those atoms and causes the atoms to split into other elements.
D) Sunflowers have evolved the ability to add electrons to the valance shell of the heavy metals,
which cause them to be no longer toxic.
E) All of the potential answers are reasonable. B. The cells of the sunflower store the
heavy metals in compartments that are not accessible to other parts of the cell and plant
Which of the following statements can be considered a hypothesis to explain how sunflowers
can tolerate heavy metals at concentrations that are toxic for other organisms.
A) Sunflowers have evolved the ability convert these heavy metals (like lead) to transitional
metals (like cobalt) by removing protons from the atoms of the heavy metal.
B) The cells of the sunflower store the heavy metals in compartments that are not accessible to
other parts of the cell and plant.

,E) While each of the potential answers is a hypothesis based on the observation, some are
inconsistent with our current scientific understandin E. While each of the potential
answers is a hypothesis based on the observation, some are inconsistent with our current
scientific understanding and thus are probably incorrect
(Picture 1) The image shows a cross section of a Vermont Lake in the middle of the winter. The

what temperature of liquid water is the average number of
hydrogen bonds per water molecule the highest?
A) 0 C
̊
B) 1 ̊C
C) Between 1 ̊C and 4 ̊C
D) 4 ̊C
to humans!). Some species, sunflowers for example, can
tolerate heavy metals (like lead and zinc) at concentrations
that are toxic for most organisms.
E) The number of hydrogen bonds per molecule is independent of temperature in liquid water.
D. 4 degrees celsius
(Picture 2) Samples of three different triacylglycerols were tested to
determine the melting point of each one. The results of the tests are shown in the graph. The
number of double bonds in each of the fatty acids A, B, and C is the same. Which of the three
triacylgcerols is likely to have the fatty acids with the longest hydrocarbon chains?
A) A
B) B
C) C
D) B or C, but not A.
E) There is not enough information to determine the answer. B. B
,What happens when an unsaturated triacylglycerol is fully hydrogenated?
A) Hydrogen is added to the fatty acid chains
B) The melting point is raised
C) The fatty acid chain is straightened
D) A and C are true
E) All of the above E. All of the above
(Picture 3) In the data set marked B: Dark colored soil, only the data set labeled "full moon"
"light coat"
has an asterisk, meaning that it is statistically different (* p<0.001). Based on how this
experiment was performed, what statistical test was used to determine the p-value and what
was the data set that was used in that comparison?
A) Student T Test; "full moon" "dark coat"
B) Chi-square test; "full moon" "dark coat"
C) Student T Test; "no moon" "dark coat"
D) Chi-square test; "no moon" "dark coat"
E) Student T Test; A: Light colored soil "full moon" "light coat" E. Student T Test; A: Light
colored soil "full moon" "light coat"
(Picture 3) Use the data represented in the figure to determine if more mice caught when the
moon was
full or when there was no moon.
A) More mice were caught when there was a full moon.
B) More mice were caught when there was a no moon.
C) There is not enough information to come to an answer.
D) While more mice were caught in one condition than the other, it is not a real answer until a
statistical analysis is performed.
E) C and D E. C and D
, (Picture 3) What is the most likely null hypothesis of this experiment?
A) Nothing matters and all of it, including our existence, is due to random chance.
B) The coat color of the mouse makes no difference to the capture of mice by a hungry owl, but
only when there is no moon.
C) The coat color of the mouse makes no difference to the capture of mice by a hungry owl.
D) The presence of the moon makes no difference to the capture of mice by a hungry owl.
E) The full moon helps hungry owls find mice. C. The coat color of the mouse makes no
difference to the capture of mice by a hungry owl.

DNA?
A) The sugar is ribose making this DNA.
B) The sugar is deoxyribose making this DNA.
C) The figure shows base-pairing, which only happens in DNA.
