Answer:
The population decreases.
Explanation:
Flood has a very adverse effect on the population of both adult and juvenile trout that lives in the streams because the trouts which has less than one year age are not good swimmers so they can't with stand with the fast flow of water during flood condition so the population of both adult and juvenile trout decreases in that stream in which flood occurs.
Answer:
20 million years
Explanation:
If we have a neutral mutation rate of one mutation per 5 million years, then the total of eight mutation between the two different species would be 20 million years. This is because both species will have 4 mutations in those 20 million years, so combined, both by 4, will have 8 mutations between them. So few mutations on so much time will result in two species that are very similar to each other even after 20 million years of evolution, even making them hardly distinguishable, especially if it comes to defining fossil records from them both. A nice example of this are the members of the felidae (cat) family, which are all very closely related, and are almost identical, thus making it extremely hard to distinguish two species of the same or similar size by their fossils.
