a. these are reactions involved in the regeneration of rubp. the reactions include an
exergonic reaction (atp adp) and the reduction of the coenzyme nadph.
b. these reactions are involved in the reduction of co2. energy is required in the form of
atp, which is hydrolyzed to adp. the substrate bpg is reduced, while the coenzyme
nadph is oxidized.
c. these reactions are involved in the fixation of co2. energy is required in the form of
adp, which is hydrolyzed to atp. the substrate bpg is oxidized, while the coenzyme
nadph is reduced.
d. these reactions are part of light reactions in noncyclic pathway. atp and nadph are
used during these reactions.
13) our domesticated honey beeoriginally from europeis slow to sting, requires
abundant flower nectar, gets up late in the morning, and stores much honey but only
produces enough new brood to swarm once a year. because the european honey bee was
performing poorly as a honey producer in south america, the african subspecies was
imported in a breeding experiment. the african honey bee formed small nests, foraged
earlier and on smaller nectar sources, produced less honey stores and more brood,
swarmed four or five times a year, and was fast to sting. however, when the african
queens escaped, the two populations interbred and the african genotype spread several
hundred miles north each year. surprisingly, a hundred miles behind the expanding
range of the african honey bees, the european and hybrid strains died out and the bees
were essentially 100 percent african. how would this be explained in evolutionary
a. gene flow is not occurring and therefore these are two separate species.
b. this is a natural consequence of the hardy-weinberg equilibrium.
c. obviously the african bee genes are dominant over the european honey bee alleles.
d. gene flow is occurring between these subspecies but the african bee is ecologically
e. this can be understood as a classic case of genetic drift.
