In a hypothetical situation, a certain species of aphid feeds only on sugar maple trees. In forests of the eastern United States, sugar maples are only one of a number of different tree species. If some of the aphids develop a strong preference for feeding on Black Walnut trees and mate only with other aphids that prefer black walnut trees, then over time, which of the following processes should occur. (Remember, the host species can be considered the aphids' "habitat."): 1.reproductive isolation 2.allopatric speciation 3.habitat isolation 4.prezygotic barriersv

Even though the ostrich is a flightless bird, ostriches still possess wings that stretch approximately two meters across when fully extended. scientists speculate that when dinosaurs became extinct, some of the birds that lived during that time became land dwellers since they were able to consume the food that the dinosaurs once ate. over time, these species grew larger and heavier. eventually, the ostrich species became too big to fly. the wings found on ostriches are known as a. analogous structures. b. homologous structures. c. vestigial structures. d. symmetrical structures.
