About 3 hours per week, so about 25 minutes every day
Answer:
C.The two species do not breed in the same area, so they are reproductively isolated by allopatry.
Explanation:
Allopatry means that these two species are geographically separated during the breeding season, so they are reproductively isolated.
Allopatric speciation is a form of speciation (creation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations reach a high level of genetic divergence. They can no longer interbreed which means they become two different species (speciation).
The Dorsal Spines give the fish, "3 Spined Stickleback", because they have hard, spines on their backs. I hope this helps!!!
