Species are single organisms that are able to reproduce, while a population is a group of species living in the same general area.
Answer:
Positive natural selection.
Explanation:
The positive natural selection is a type of natural selection that increases the frequency of an allele or trait when it is advantageous for the population. What happened in the example is that the mouth with the slight change in morphology (trait) was more advantageous for the population in the south in relation to the ancestral morphology (still preserved in the population in the north), and therefore its frequency increased. This, in turn, is due to the fact that the food (prey) is not the same in the two habitats (north and south). The specific prey in the south, caused the new morphology to be selected, (increasing the frequency of individuals with the new mouth), becasue probably that trait allows the trouts in the south to hunt more effectively.
D. There are no major fault lines or hot spots close by.
Why?
Because "They don’t occur anywhere else other than along the Ring of Fire" is incorrect, the Ring of Fire is just a place where many volcanoes are.
Because "The composition of the rock in that area is not conductive to eruptions." they type of rock doesn't play that much of a role in the formation of volcanoes
Because "The magma doesn’t have enough silica or gas to form an explosive eruption." It isn't a gass that is found, it is the build up of pressure from fultlines moving and things on the inside of the earth.
