ANSWERS RATED A+
✔✔The ______ glands produce chemicals known as "footprint" pheromones -
✔✔arnhart
✔✔Wax is secreted by honey bees by paired glands in their _____ and then harden into
_______. - ✔✔abdomen, scales
✔✔What part of the digestive system runs through the bee's thorax? - ✔✔esophagus
✔✔The Corpora Cardiaca is the only source of Juvenile hormone (JH). - ✔✔false
✔✔The honey bee digestive tract expands and contracts with the _____, which is found
in the hindgut. - ✔✔rectum
✔✔What part of the drone reproductive tract remains in the queen for a while after
mating? - ✔✔endophallus
✔✔Alarm pheromone production increases as worker bees age. - ✔✔true
✔✔A successful nectar forager returning to the nest would have a closed
proventriculus. - ✔✔true
✔✔What effects do direct muscles have on the honey bee wing? - ✔✔change angle
and roation
(the major movements creating wing beats are from the indirect muscles, but direct
muscles do play a smaller role)
✔✔Adipocytes are cells of the fat body that synthesize wax - ✔✔false
✔✔The nutritional quality of pollen varies based on its total protein content and also -
✔✔its specific amino acid profile
✔✔What is the actual difference between bright white vs. darker capped honey on the
comb? - ✔✔presence or absence of air trapped between the wax cap and honey is
responsible for the difference in appearance
✔✔Worker larvae receive a larger proportion of nurse bee hypopharyngeal gland
secretions than mandibular gland secretions in their diet - ✔✔true
✔✔The study of pollen is known as Palynology - ✔✔true
,✔✔All nectaries are located within flowers - ✔✔false
✔✔Nectar being transported back to the hive in the forager's honey stomach is
unchanged from when it was still in the plant nectary - ✔✔false
✔✔Why do honey bees show a preference for contaminated water over a pure source -
✔✔Due to dissolved minerals, especially salts
✔✔Why are diploid drone eggs produced fairly rarely in nature? - ✔✔Many possible
alleles at the sex-determining locus
✔✔Brood survival in drones averages around 60%. Brood survival in _____ averages
around 53%. - ✔✔queens
✔✔What is meant by the term "bipotent" as it refers to the fertilized honey bee egg? -
✔✔It has the ability to become either a queen or a worker
✔✔Approximately when is the "critical age" concerning worker vs. queen development?
- ✔✔3 day old larva
✔✔Inbreeding may cause the occurrence of diploid drones to increase - ✔✔true
✔✔Honey bee larva fed like queens starting at 1 day of age are likely to be - ✔✔queens
of high reproductive quality
✔✔What is the difference between a queen cell and a queen cup - ✔✔the presence of
an egg/larva in a queen cell
✔✔What is most likely to occur if two emerged queens are present in one colony at the
same time? - ✔✔queen duel to the death
✔✔What is the fate of a drone that is lucky enough to mate with a queen - ✔✔death
stemming from the eversion process
✔✔Afterswarms are headed by virgin queens - ✔✔true
✔✔Drone congregation areas (DCAs) are very unstable and will change locations
annually - ✔✔false
✔✔Looking at the timing of queen sexual maturity, what happens around day 7? -
✔✔"nuptial" or mating flights begin
, ✔✔Mature drones wait in places called ____ to try and mate with a queen on her
mating flight - ✔✔drone congregation areas
✔✔Individuals of a "superorganism" are usually able to survive and flourish by
themselves as well. - ✔✔false
(It takes at least several hundred workers and a queen to have a viable colony in honey
bees)
✔✔Which of the following is one of the only two known species of eusocial mammals? -
✔✔naked mole rat
✔✔What is an incentive for offspring to remain at the nest in the naked mole rat? -
✔✔increased workforce to dig through hard soils
✔✔Which of the following would increase "C" of Hamilton's equation (rB>C)? - ✔✔more
nesting sites open, making altruist is more likely to successfully rear its own offspring
✔✔Eusociality has evolved only once in the animal kingdom - ✔✔false
✔✔Eusocial organisms are more likely to sacrifice their lives to defend their colony -
✔✔true
✔✔Which of the following is not a defining characteristic of eusociality? - ✔✔hidden
nests
(Hidden and/or well defended nests are typical, but not a defining character)
✔✔Which of the following is not a way in which parents might manipulate their offspring
into performing altruistic behaviors such as brood care? - ✔✔Offspring forced to leave
the nest area upon reproductive maturity
✔✔The death of a few individuals often has little effect on the functioning of the
superorganism as a whole - ✔✔True
✔✔The social structure of which member of Apoidea tends to break down once males
are produced? - ✔✔Bombini: bumble bees
✔✔In general, beekeepers can observe that a dark colored queen bee will have dark
sons (drones) but her daughters (workers) are often more variable. How might you
explain this? - ✔✔drones have only maternal genetics while daughters have paternal
component
