Honey bee workers from a colony in North Carolina are visiting two food sites, A and B, at 6 am as shown below. Site A is 1500 m from the hive; site B is 300 m from the hive. Which of the following statements is true regarding the genetic basis of the bees’ ability to track the passage of time and compensate for the movement of the sun? a. The bees’ clock mechanism is based on the Amfor gene, which causes a build up of AMFOR protein in the corpora pedunculata that activates the Gp9 and UU genes, whose products degrade AMFOR in a 24 hour cycle. b. The bees’ clock mechanism is based on the per gene in the optic lobes, whose activity has a 24 hour cycle regulated by the dbt and tim genes. c. The bees’ clock mechanism is based on alternating expression of two alleles for the for gene in the subesophagael ganglion: the R allele which is active at night and the s allele which is active during the day. d. The bees’ clock mechanism is based on levels of eclosion hormone released from the pars interecerebralis, which increases in response to the dbt gene and decreases in response to the tim gene in a 24 hour cycle
