4) figure a is an 8-cm. cube. figure b is eight, 4-cm cubes. figure c is sixty-four, 2-cm
cubes.
what figure has the greatest surface area (height x width x number of sides x number of
cubes)?

9) when he arrived at the galpagos islands, darwin did not observe the amazing
tool-using “woodpecker finch” that can modify twigs to pry out grubs. because there are
no true woodpeckers on the galpagos islands, this behavior allows this finch to exploit
an untapped food source. however, not all members of this species exhibit this behavior,
which is probably learned from watching other finches. therefore,
a. young isolated at hatching will not know how to do this.
b. it is probably not “hardwired” in the brain as a behavior passed on genetically.
c. there must be a great advantage to reaching this food source for this learned behavior
to be repeated by most descendants of each generation.
d. as an acquired characteristic, in a strict sense this is not part of the adaptive radiation
of finches on the galpagos.
e. all of the choices are correct.
