The correct answer is a bond of language and culture
When the empire fell, the military disbanded more or less and the country was in chaos. That is why a bond of language and culture kept the decentralized mess of an empire still going.
Answer:
The climate region labeled with number 4 is the tundra, characterized by a very cold and dry climate, and low diversity of organisms that are highly specialized.
Explanation:
The tundra is a climate region that is found in the northernmost parts of Asia, Europe, and North America. This climate region is characterized by very low temperatures are year-round, and even when it is summer the temperatures are relatively low. The precipitation levels are also very low, and when there are any they come in the form of snow. The winds tend to be very strong and very cold.
The animals and plants that live in the tundra are all highly specialized. The plants tend to be very small, close to the ground, and are able to withstand extremely cold temperatures and a very long period of being inactive. The animals have very thick fur, often double layer, preserve a lot of fat, have wider nostrils, wider paws, and their ears tend to be very small to avoid freezing. Some of the plants that can be found here are the lichens and mosses, while from the animals there are polar bears, Arctic foxes, lemmings, walruses, multiple species of seals...
Answer:
In the exceptionally cold winter of 1997, Lake Superior froze over between the Wisconsin mainland and Isle Royale. A pack of 8 wolves crossed the ice and reached Isle Royale, an island where they encountered a population of about a dozen wolves. It is estimated that the wolf population on Isle Royale has been isolated for over 100 years (~10 generations). The pack of 8 wolves that crossed the ice would be referred to as <u>founder population</u> and if the wolves interbreed with the island population, <u>genetic drift</u> will occur.
Explanation:
The founder effect occurs when a portion of a population (i-e the founders) separates from the old population to start a new population with different allele frequencies. Hence the pack of 8 wolves that crossed the ice would be referred to as <u>founder population</u> in the given scenario.
Genetic drift is defined as change in the allele frequencies in a population due to chance event. As in the given scenario, the pack of 8 wolves that crossed the ice, interbreed with the island population, thus change in the allelle frequency is occuring in the population , hence <u>genetic drift</u> will occur.
Answer:
earthquakes, tsunamis, and volcanic eruptions
Explanation:
In recent years, Japan ranked among the countries with the most natural disasters. Since the country is situated along the Ring of Fire, an area where several plates meet, it is vulnerable to a lot of natural disasters such as earthquakes, tsunamis, and volcanic eruptions.
