9. A sample of eDNA from the ancient ecosystem contained genetic material originating from an ancient poplar tree. Scientists identified the corresponding chromosome of modern poplar trees and compared the ancient and modern DNA molecules. The DNA was not identical. Which statement most likely explains why the DNA from modern poplar trees is different from the DNA of ancient poplar trees?
a)
Ancient poplar trees reproduced asexually by producing seeds, but modern poplar trees reproduce sexually.
b)
Favorable environmental conditions reduced the rate of cellular division, resulting in the production of fewer daughter cells
c)
Mutations made during DNA replication were not corrected before protein synthesis began, causing mutations to accumulate in the popular genome over time
d)
Independent assortment of chromosomes during meiosis enabled ancient poplar trees to produce identical offspring, but modern poplar trees produce genetically unique offspring

a)
The first codon was UGG; the final codon was AUG.
b)
The first codon was AUG; the final codon was UAA, UAG, or UGA
c)
The first codon was UGG; the final codon was UAA, UAG, or UGA
d)
The first codon was AUG; the final codon was AUG.

12. Which correctly shows (left to right) what the following boxes should be filled with.
a)
Fish, frog, bird, lizard, rodent, gorilla
b)
Fish, lizard, bird, frog, rodent, gorilla
c)
Fish, bird, lizard, frog, rodent, gorilla
d)

13. A fish species that lives only in caves produces more of a protein called SSH compared to closely related fish species that do not live in caves. The extra protein causes the eye cells to die and be absorbed back into the body. Which statement best explains how natural selection caused this phenomenon?
a)
The cave-dwelling fish ancestors had this mutation, which left them eyeless, so they found caves to live in for protection
b)
With less light in caves, the eyes of cave-dwelling fish were more likely to mutate since they were not being used
c)
Animal cells make less SSH when there is no light, so cave-dwelling fish species can adapt to low-light environments more quickly
d)
An increase in SSH happened after cave-dwelling fish started to live in caves and was beneficial because it eliminated eyes, which were no longer useful

14. Which answer choice is filled out correctly for the drop down boxes below:
a)
Chemical reactions; many of the same atoms
b)
Physical reactions, mostly different atoms than those
c)
Chemical reactions; mostly different atoms than those
d)
Physical reactions, many of the same atoms

16.
a)
The amount of sugar present in the insect
b)
The amount of oxygen consumed by the insect
c)
The amount of mitochondria involved in producing ATP
d)
The amount of ATP produced through cellular respiration
14.
17. Researchers are investigating ways to increase the efficiency of an important protein called Rubisco, which aids in carbon fixation in plants.
How would the increase in the efficiency of this protein most likely affect the carbon cycle?
a)
Increased Rubisco efficiency would increase the amount of carbon released by the biosphere and increase atmospheric carbon
b)
Increased Rubisco efficiency would limit the amount of carbon needed to build larger organic molecules during the process of photosynthesis
c)
Increased Rubisco efficiency would decrease the amount of carbon in the atmosphere and increase the amount of carbon in the biosphere
d)
Increased Rubisco efficiency would limit the amount of carbon dioxide released during photosynthesis and prevent the formation of glucose during cellular respiration.
