UNC BIOL 278 Final Exam
Suppose that two sets of fish were raised in an oxygen rich or oxygen poor
environment. Each set was tested for aggression by their response to their own
reflection. The fish raised in oxygen poor environments were more aggressive than their
oxygen-rich counterparts. What do these results tell us? - ✔️✔️The experience of
being oxygen starved can increase aggressive behavior - notice the language, CAN
increase. Correlation does not equal causation.
As Chief Animal Behaviorist of the Galaxy, you are summoned to Planet X to consider
the behavior of the male backup bug, which approaches potential mates backwards.
You are asked to explain this with an experimental design - which is best? - ✔️✔️Use a
phylogenetic approach and compare the courtship behaviors of backing bugs to other,
closely related creatures
When adult seagulls arrive at their nests, they feed the waiting chicks only if the chicks
actively beg for food. Because all chicks beg for food in the same way, it was initially
thought that begging was innate behavior. What results demonstrated this was only
partly true? - ✔️✔️Observation showed that the chicks know how to approach their
parents and close mouth to indicate that they need to be fed, but chicks raised by
humans and presented to fake parents could not appropriately grasp the parents' bill
like those raised with parents
If the older bees in a hive suddenly failed to transfer ethyl oleate to younger bees when
providing them with food, what would happen? - ✔️✔️The younger bees would develop
into foragers prematurely
On a stroll through your neighborhood one evening, you notice that robins are feeding in
eveyone's yard, except for the three houses with sloping very lush, and weed free
lawns. Everyone else has patchy, flat lawns with lots of dandelions. What can be
correctly stated about the use of your neighbors' lawns by robins? - ✔️✔️There is a
correlation in the neighborhood between robins and flat lawns. Remember, correlation
does not equal causation, so do not answer anything definite without proper
experimentation.
A study was done on crab eating macaques return to the same tree to sleep every
night. Which of the answers below describe the study and its conclusions? -
✔️✔️Researchers did an observational study and found a correlation between having
another sleeping tree in sight and where their travel routes were.
