You are trying to determine if honeybees have social immunity to nosema, an economically devastating parasite that attacks adult honeybees. You mark some honeybees with a spot of red dye and expose them to a solution containing a sublethal dose of the parasites. Another set of honeybees is exposed to the same solution without parasites. After this exposure, you mix some of the unmarked bees with
the marked bees (Mixed Group). The rest of the unmarked bees are not mixed with other bees (Unmixed Group). If honeybees can develop social immunity to nosema, what are the expected results of your experiment?
A. The marked honeybees will mostly survive, but the unmarked bees of both groups will mostly die.
B. The unmarked honeybees in the Mixed Group will have a higher survival rate than those in the Unmixed Group.
C. The unmarked honeybees in the Mixed Group will have a lower survival rate than those in the Unmixed Group.
D. The unmarked honeybees in the Mixed Group will have a higher survival rate than the marked honeybees.
E. There is no way to predict the results based on the information given.
B. The unmarked honeybees in the Mixed Group will have a higher survival rate than those in the Unmixed Group.
