Answer:

The order in which migration of homo sapiens occurred: (†, Ti, TL, 1, and fi).

Africa
Europe
Asia and Australia
North America
South America.

Explanation:

According to scientists, homo sapiens happened to be the only surviving human species through evolution, whom we call commonly humans. They assert that homo sapiens are the first modern humans able to adapt and cope with changes.

It is considered that humans, at first were suited to dry regions such as Africa, and from there, after evolution they began to spread around the world.

So, the chronological order in which this migration of homo sapiens occurred around the world is:

First, homo sapiens spread in Africa, but not all parts of the continent.

From Africa, they began to migrate to Europe and Asiatic lands, as the connected landmass enabled them to travel into these region. From Europe, they migrated to Asia. And from Asia, they migrated to Australia in canoes. During the Pleistocene Ice Age, a land bridge was formed between Asia and North America, which enabled homo sapiens to travel to North America. And from North America, humans migrated to the South America.

So, the correct order is Africa, Europe, Asia, Australia, North America, and South America. (†, Ti, TL, 1, and fi).

Jerome operates under heteronomous morality while Hani is operating under autonomous morality. Under Jerome's schema, the outcome of the action and the rules of the world determine the morality of an action, without understanding the intentions or the mitigating factors that might be at play. Autonomous morality, however, sees that there are shades of grey to every situation and that morality does not always require a punishment for every action or transgression.

NNADVOKAT [17]

The western roman empire was weakened by the high cost of defending the empire.

At its zenith, the Roman empire stretched from the Middle East to the Atlantic Ocean. It being a vast territory, was not easy to govern and due to its vastness the empire faced logistical as well as administrative issues.

Even though they had excellent road systems, the Romans were still not able to effectively manage their territories. They had to struggle in order to maintain enough resources and troops so that they could defend themselves from the rebellions and outside attacks. Emperor Hadrian even constructed a wall in Britain so as to keep the enemies away.

Answer:

Costs go down

Explanation:

In Microeconomics, economies of scale can be defined as cost reductions or cost advantages that arises when a business entity is increases its production or are large in size.

This ultimately implies that, when an organization chooses a convenient scale of operation or reduce its scale of production, this would lead to a reduction in the cost of production and consequently, some benefits such as lower long-run average cost, increased sales, profits and lower cost price for the consumers of these finished products.

Furthermore, economies of scale is evident when employees are able to specialize in a specific task. This is so because having a good number of professionals and experts would increase the level of production or output, as they are quite conversant with the best method of production, time management and efficiency.

Average Total Cost (ATC) can be defined as the overall cost of production divided by total output of production. It is calculated by dividing total cost by total output of production or by adding TVC and TFC.

$ATC = TVC + TFC$

Generally, the shape of the average total cost (ATC) for a firm experiencing economies of scale is horizontal and downward sloping.

This ultimately implies that, for the average total cost curve of a firm with economies of scale, the costs go down as output increases.
