Question:
5. Communication has often evolved through co-opting
and modifying behaviors used in another context. For
example, the elimination of wastes can also be used:

in order to avoid a costly fight.
B. to advertise to other individuals in order to attract
mates.
C. All of these choices are correct.
D. to strategically mark "ownership" of particular

,Question:
6. Honeybees use movement in specific patterns that
convey information about the location of a food source.
Which statement accurately describes the waggle
dance?
A. If the food source is far away, the bee spends less time
waggling up the middle of its circle.
B. The waggle is "danced" by the queen bee.
C. Finding the food source that is at a 45-degree angle
requires that the dancer's "line" be 45 degrees to the
angle of the sun.
D. Distance to the food source is conveyed by a waggle
up the middle of the bee's circle.
E. Foragers waggle back and forth while moving forward
and backward. Then they move backward in the circle
and repeat the waggle and circle back the other way.
Answer:
D. Distance to the food source is conveyed by a waggle up the middle of the
bee's circle.
