Bio 1500 Final Exam Mizzou Questions
and Answers 100% Pass
Recognize dragonflies as formidable aerial and aquatic predators - ✔✔Dragonflies live
in water for the first two years of their life. After this adult dragonflies hunt other flying
insects while they are flying themselves; they cannot feed while walking or sitting.
Identify dragonflies as ancient insects (when, what, why) - ✔✔Carboniferious,
meganura, first insects to fly, selection pressures
Develop more than one hypothesis for why dragonflies were so big - ✔✔atmospheric
PO2, and the lack of aerial predators
Rank the importance of team-working skills, content knowledge, communication skills,
learning skills, ... for employers and graduate school admission - ✔✔1. team work -last
is content knowledge
Memorize the dates of major milestones in the history of life on earth, as indicated in
the online learning module - ✔✔1. universe formed- 13.7 bya
2. earth formed- 4.5 bya

4. oldest rocks formed- 3.8-4bya
5. oldest fossils (or signs of life) 3.5-3.8bya
6. Cyanobacteria- 2500 mya
7. Eukaryotes- 2000 mya
algae- 1200 mya
"snowball" ice ages- 750-600 mya
8. first animals 590 mya
9. Cambrian explosion 545-520 mya
10 carboniferous- 360-330 mya
11. first dinosaurs- 230 mya
12. birds 150 mya

14. modern humans 200,000 years ago
Recall environmental characteristics of the Carboniferous time - ✔✔lots of greenery,
atmospheric PO2 was 35%

,Relate the changes of O2 levels in the atmosphere to biological events in the history of
life. - ✔✔photosynthesis evolved because of cyanobacteria, at first the rocks oxidized
and used up all the oxygen. Once they reached a certain point, life exploded on earth
because of the available oxygen. Great oxygenation event caused the ozone to form,
mass extinction because excess O2. O2 reacted with methane- eventually caused
snowball ice age
Recognize that the geology of earth has been dramatically changed by biology - ✔✔the
development of photosynthesis and the ricks used up free O2
Describe the mechanism of diffusion at the level of single particles - ✔✔random
movement
Describe the pattern observed due to diffusion and the level of many particles - ✔✔high
to low concentration
Explain how the behavior of single particles explains the observed pattern at the many
particles level - ✔✔they continue to move from high to low concentration until the
gradient no longer exists (reaches equilibrium)
Explain the relationship between distance and time during diffusion and recall the
important consequence for transport in organisms by diffusion - ✔✔Diffusion is only
efficient over short distances; this limits the maximum size of the organism because of
its limitation of O2 transportation

, Determine whether a particular set of data would be best depicted using a scatterplot,
bar graph, or line graph - ✔✔categorical= bar graph, change over time= line graph,
correlation in events= scatter
Describe the situations in which a logarithmic axis is preferable to a linear axis -
✔✔typically, a log axis is helpful when you have a large range of data
Recognize how graphs can be used to mislead people - ✔✔the scales on the graphs can
be manipulated to look like there is a large difference between different variable when
there really is not
Formulate a hypothesis about the factors that allowed insects to be so big, based on the
findings of Clapham and Karr - ✔✔PO2 of the atmosphere and predation
Describe and interpret Figure one of Clapham and Karr - ✔✔The y axis on the top part
is the length of the insects' wings in millimeters. The y-axis on the bottom graph shows
the atmospheric environmental oxygen concentrations. The x-axis on the top labels the
species as well as the time periods, while the x-axis on the bottom shows the age in
million years. The black bars represent more than 50 measurements that occurred in
that "bubble," this is to indicate that a lot of measurements were taken without
crowding the graph. The top and bottom graphs are displaying the correlation of
atmospheric PO2 and the wingspan length over time.
