The best explanation for how humans populated the Earth is a. they migrated from Asia to other continents over the last two million years.
b. they migrated mostly over land from Africa over the last eighty thousand years.
c. they developed varied human species in different places over millions of years.
d. they traveled by boat from Africa to other continents over the last forty thousand years.
The best explanation for how humans populated the Earth is they migrated mostly over land from Africa over the last eighty thousand years. Option B is the correct answer.
Scientific evidence, such as fossil discoveries and genetic studies, supports the theory that humans originated in Africa and gradually spread out to other parts of the world. This process, known as human migration, occurred over a long period of time, with the majority of migration taking place over land. Option B is the correct answer.
The Out-of-Africa theory proposes that anatomically modern humans evolved in Africa around 200,000 years ago and then migrated to other continents. This theory is supported by fossil evidence, such as the discovery of early human remains in Africa, which are considered ancestral to humans found in other parts of the world. Genetic studies have provided further evidence for human migration out of Africa. By comparing the DNA of populations from different regions, scientists have identified genetic markers that indicate common ancestry with African populations. This suggests that populations in other parts of the world descended from early human migrants who left Africa.

Which of these choices best describes italy in the 15th century? a unified nation one large feudal estate a collection of small kingdoms and city-states a collection of spanish and french colonies
The correct answer is - a collection of small kingdoms and city-states.
Italy, in the 15th century, was not a unified country, but instead, there were numerous small kingdoms and city states on its territory. These small kingdoms and city-states were varying in military and economic power, but in general, for small territories, they were respectably powerful.
All of these small kingdoms and city-states were ruled by local powerful families, whose main occupation was usually trade, apart from the Papal state, where the leader was the Pope of the Catholic church.

Further detail:
The Industrial Revolution had its beginning in Great Britain, and eventually spread from there. Once the United States became involved, especially in the "Second Industrial Revolution" years (1870-1914), the size and resources of the country allowed the US to become a bigger industrial power than the nations of Europe.
Industrialization also led to the phenomenon of urbanization -- the movement of people away from the rural countryside and into cities. That led to other issues, like pollution and crime problems in cities. So sanitation and health measures were enacted, and the first police forces were formed.
The overcrowding conditions also meant poor living conditions in tenements and slums. The condition of these sorts of neighborhoods was documented by Jacob Riis, a police reporter in New York. In 1888, Riis took pictures of what life was like in New York City's slums. Using his own photos as well as photos gathered from other photographers, Riis began to give lectures titled, "The Other Half: How It Lives and Dies in New York," in which he would show the pictures on a projection screen and describe for viewers what the situations were like. He gave his lectures in New York City churches. In 1989, a magazine article by Riis (based on his lectures) was published in Scribner's Magazine. The book version was then published in 1890 as How the Other Half Lives: Studies among the Tenements of New York. Riis blamed the poor living conditions on greed and neglect from society's wealthier classes, and called on society to remedy the situation as a moral obligation.
Why Igneous materials found along oceanic ridges contain magnetic iron particles that show reversal of magnetic orientation. This is evidence that
Igneous materials in oceanic ridges contain magnetic iron particles oriented according to the Earth's magnetic field. The varied orientations provide evidence of geomagnetic reversals and the processes of thermal remanent magnetization and seafloor spreading.
Explanation:The presence of magnetically aligned iron particles in igneous rocks found along ocean ridges is due to the Earth's magnetic field. This is evidence that the Earth's magnetic field has reversed its polarity multiple times throughout history - a phenomenon known as geomagnetic reversals. When these rocks form from cooling magma, they take on the current orientation of the Earth's magnetic field. Over time, as new rock forms and the Earth's magnetic field changes, a record of these changes is 'frozen' into the rocks in a process called thermal remanent magnetization. This process provides strong evidence for the theory of plate tectonics and seafloor spreading.

Which statement is true about market economies?
Government goals drive business decisions.
People have the freedom to choose their jobs.
Several pure market economies exist around the world.
They combine elements of traditional and planned economies.
Final answer:
A market economy is an economic system where individuals have the freedom to choose their jobs, and the government does not drive business decisions. Most economies in the real world are mixed, combining elements of command and market systems.
Explanation:
A market economy is an economic system where individuals have the freedom to choose their jobs. They can decide what to produce, who to work for, and how to obtain the goods and services they need. In a market economy, the government does not drive business decisions; instead, businesses are driven by the pursuit of profit and market demand.
While there are several pure market economies in theory, in reality, most economies are mixed, combining elements of command and market systems. These mixed economies have a greater degree of government involvement in economic decisions than pure market economies.

The Atlantic Coastal Plain is located in the..?
The Atlantic Coastal Plain spans from New England to Texas along the eastern coast of the United States, known for its gradual slope toward the ocean and historically swampy areas.
Explanation:The Atlantic Coastal Plain is located in a vast area along the eastern coast of the United States, stretching from the coast of New England down to Texas. This region is characterized by a very gradual slope toward the sea, making it the flattest region in the country. The coastal plain begins as a narrow strip in New England, widening significantly in southern New Jersey, and extending across the eastern thirds of several states including Virginia, the Carolinas, Georgia, and encompassing all of Florida. Additionally, southern Alabama and Arkansas, eastern Texas, and all of Louisiana and Mississippi are part of the Atlantic Coastal Plain. The plain's features include a very gradual slope towards the ocean, historically swampy areas due to poor drainage, and a landscape dotted by bays, bayous, and flat islands.
which of the following form part of the borders of almost all of the central american countries?
a. caribbean sea and mexico
b. caribbean sea and pacific ocean
c. North america and south america
d. pacific ocean and honduras
The answer is b. Caribbean Sea and Pacific Ocean, as almost all Central American countries are bordered by these two bodies of water to the east and west respectively.
Explanation:The correct answer to this question is b. Caribbean Sea and Pacific Ocean. Indeed, Central America is geographically positioned between the Caribbean Sea to its east and the Pacific Ocean to its west. This configuration results from Central America's land bridge formation, which extends from Mexico to the Isthmus of Panama, the narrowest point before South America. The region's physical environment also dictates that, except for Belize, the majority of Central American countries have coasts on both the Pacific and Atlantic Oceans (the Caribbean Sea being part of the Atlantic Ocean). Considering this, while other features such as the Gulf of Mexico and various countries like Honduras also occur in Central America, they do not border almost all of the Central American countries like the Caribbean Sea and Pacific Ocean do.
