The goldenrod gall fly mates and lays its eggs on the goldenrod plant and the larva live inside the plant. When a new species of goldenrod (goldenrod B) moves into the range of the fly some of the flies move to goldenrod B. How does this process allow for sympatric speciation of the flies? Group of answer choices A. the two plants have different chromosome numbers B. the flies only reproduce on their host plant C. hybrids are always more successful than either type of fly D. a predator keeps the two types of flies separated E. the two plants occur in different geographic areas

Imagine a field of monkey flowers. Some of them are pink and others are red. It turns out that the pink flowers are pollinated mostly by bumblebees, whereas the red flowers are pollinated mostly by hummingbirds. As a result pink flowers are fertilized mostly by pollen from other pink flowers, and red flowers are fertilized mostly by pollen from other red flowers. The pink and red flowers have become separate species. What type of speciation is this? Sympatric speciation type (my answer) What mechanism of reproductive isolation was involved? ??

Fruit flies of the genus Drosophila are distributed worldwide, but 30-40% are found on Hawaiian islands. How can you explain this distribution pattern? I’m addition, most species that have been identified are almost indistinguishable from other species and yet vary few hybrids have ever been observed. How might this phenomenon be explained?
Hybrid breakdown refers to which situation? Group of answer choices Two species can hybridize but their offspring do not develop fully or are frail and will not survive to reproduce. Two species can hybridize but their offspring are sterile. None of the above Two species can hybridize and their offspring are ok and can have offspring, but the next generation are more likely to die or will be sterile. Two species can hybridize and fuse back into one species.
which statement is false? 1)In the context of the evolution of senescence, the aphorism "live fast and die young" means that organisms with a more risky behavior will have a shorter life span. 2)Allopatric speciation is a type of speciation process that takes place in different geographic locations.
