Answer:
The author starts the story with a more serious and somber tone, but ends the story with a lively and exciting tone.
Explanation:
"Po-No-Kah" begins with the history of the first English colonists in North America. This beginning has a dark, serious and sad tone, because, as we know, the Pioneers had many difficulties in establishing themselves in America, in addition to being an environment that did not promote enough resources for their survival, they had to be constantly alert, afraid that the natives would attack them.
The story ends, however, with the release of the Hadeeman family from their captors, this is a happy moment, where the whole family, with the exception of the pet dog, left unscathed. This part of the story has a happy and lively tone.
The African trade in gold and salt caused the Ghana Empire to rise to prominence, and the disruption of that trade led to its decline. During its time, Ghana was one of the richest polities in Africa.Though Ghana was not rich in natural resources itself, it was located along an important trade route between gold- and ivory-producing areas in the south and salt miners in the Sahara desert to the north. As a result of this strategically important location, Ghana became a wealthy entrepot.
Though the exact origins of Ghana are clothed in mystery, tradition places the empire's origins in the fourth century AD. By the ninth century, the area had become affluent according to accounts by Muslim traders who began to visit the area. These traders from the north continued to develop the trade, linking its gold resources with the vital markets in the Mediterranean region, and the empire grew larger by incorporating its neighbors.
The decline of the empire started in the 11th century, when the Almoravids, a militant confederation of Muslims, began to attack the empire and even conquered it for a time. Though their grip on power did not last long, the chaos they brought to the region destabilized trade, hurting the empire's sources of income. Decline ensued. The remnants of Ghana were incorporated into the Mali Empire in 1240.

The differences in the wild and hatcheries make it so the different salmon adapt differently and have different traits.
If salmon are split up into different habitats, one being in the wild and one being in captivity, they will eventually have different adaptations from each other and their offspring will develop traits that are better suited for their environment.
Wild salmon and salmon that are raised in captivity are going to be very different from each other. The salmon in captivity do not have to actively hunt for their food, be wary of certain predators, or may not want to reproduce.
Taking these factors into account, it is very possible that the salmon raised in captivity will have reduced reproductive success compared to the salmon that thrive in the wild. Along with this, they would most likely have many genetic differences from each other and other traits that better adapt to their living situations.
