Card 2 / 112: Determine if the examples below (I through III) are due to the effects of the environment on phenotypic plasticity or evolutionary change. I. An individual Common Ice Plant has the ability to change from C3 photosynthesis to CAM photosynthesis when it becomes stressed by low water or high salinity. II. When plants become too dense and competition is high, some Aphid species grow wings between generations to enable dispersion, and then the next generation is without wings. III. Bats are able to fly with wings that are paws with really long fingers and skin stretched between them; one way this could happen is if these finger bones grew at a faster rate than the rest of the body.
A) I = plastic phenotype, II = phenotypic plasticity, III = evolutionary change
B) I = plastic phenotype, II = evolutionary change, III = evolutionary change
C) I = evolutionary change, II = evolutionary change, III = plastic phenotype
D) I = evolutionary change, II = plastic phenotype, III = plastic phenotype
