Answers
Recognize dragonflies as formidable aerial and aquatic predators CORRECT ANS-
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) CORRECT ANS-Carboniferious,
meganura, first insects to fly, selection pressures
Develop more than one hypothesis for why dragonflies were so big CORRECT ANS-
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 CORRECT ANS-1. team
work -last is content knowledge

Answers
Relate the changes of O2 levels in the atmosphere to biological events in the history of life.
CORRECT ANS-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 CORRECT
ANS-the development of photosynthesis and the ricks used up free O2
Describe the mechanism of diffusion at the level of single particles CORRECT ANS-random
movement
Describe the pattern observed due to diffusion and the level of many particles CORRECT
ANS-high to low concentration
Explain how the behavior of single particles explains the observed pattern at the many
particles level CORRECT ANS-they continue to move from high to low concentration until
the gradient no longer exists (reaches equilibrium)

Answers
Explain the relationship between distance and time during diffusion and recall the important
consequence for transport in organisms by diffusion CORRECT ANS-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 CORRECT ANS-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 CORRECT
ANS-typically, a log axis is helpful when you have a large range of data
Recognize how graphs can be used to mislead people CORRECT ANS-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 CORRECT ANS-PO2 of the atmosphere and predation
