which statement describing the results of this
investigation?
A. Mutation is responsible for the survival of all flies in the control jar.
B. In all environments, wingless flies are better
adapted for survival than winged flies
C. The type of food provided in the experimental jar did not promote survival of winged flies.
D. The flypaper is a selecting agent against the
winged flies
