Answer: b
An inherited modification of structure or function that allows an organism to survive and reproduce in its environment.
Explanation:
Adaptation helps an organism to become better suited to survive and reproduce in its environment. It is change in an organism's structure or behavior.
Change in physical features of an organism is considered as structural adaptation. Example- fur in bear
Change in the way an organism does things to survive is called behavioral adaptation. Example- bird calls and migration from one place to another.
Adaptation is an essential feature that helps an organism to better servive in the environment. In case, an organism fails to adapt to changes in its environment, its immune system becomes weak and fails to work. This threatens its life and it becomes ill. This may also result in its death.

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.
