What difficulties did Schroeder face and why?

Answer:  They didn't know how to maintain irrigation systems across villages, the system also got clogged.

explanation  : hope that helps  

Sumerian farmers, after creating irrigation systems, faced the new challenge of water management. The erratic and unpredictable nature of the Tigris and Euphrates rivers made maintenance and effective functioning of these systems difficult, while also increasing labor demands.

After Sumerian farmers innovated and implemented irrigation systems to support their agriculture, new problems arose, primarily issues related to water management. The Sumerians had successfully managed to control the flow of water from the Tigris and Euphrates rivers to maximize their agricultural yield. However, the challenge lay in maintaining these systems. The water flow in these rivers was erratic, with flooding being frequent and unpredictable, which complicated efforts to effectively use and manage their irrigation systems.

Maintaining and ensuring the effective functioning of these systems required labor, with these tasks often falling onto the farmers themselves or the ruling class. In essence, while the irrigation systems led to improved crop yields and allowed for the development of early urban centers, they also increased labor demands and introduced new complexities and responsibilities in terms of water management and system maintenance.

The Huns, under Attila’s leadership, invaded and occupied the borders of Roman Empire, causing significant displacement and pressure on Germanic tribes and other groups. These mass migrations into Roman territories brought with them disturbances and chaos, contributing to the destabilization and eventual fall of the Roman Empire.

These pressures and invasions led to the migrations of various groups, including the Germanic tribes, into the Roman territory., Remarkably, the Huns were led by Attila, who was notorious to Romans due to his ruthless plundering across Europe. His vast empire integrated various peoples as they moved westward and even reached Gaul. However, with Attila’s death in 454, the Hun Empire ultimately collapsed..

Germline mutations occur in gametes. Somatic mutations can occur in other body cells. Chromosome alterations refer to mutations that alter the chromosome's physical composition. Point mutations change a single nucleotide.

The effects of mutation could be positive, negative, or neutral depending on the circumstance or region. Most non-neutral mutations are detrimental. With each additional base pair that a mutation alters, the effect and likelihood that the mutation will be deleterious rises.

The correct answer is C) The North remained segregated by habit, not by law.

The statement about race relations in the North and South after Reconstruction that is true is "The North remained segregated by habit, not by law."

After the Civil War, the United States government had officially ended slavery in the country. President Abraham Lincoln tried to reintegrate the Southern States to the Union during the Reconstruction period, but his anxiety to do it quickly allowed the Southern States leeway to do Reconstruction in their own terms. In the North, where many people had supported abolitionism before the Civil War, they were more receptive to integrate black people in society, although the process was not as easy as in theory it should have happened.

For example, one notable patroon was the Van Rensselaer family, who at that time owned a large estate called Rensselaerwyck along the Hudson River. They enjoyed significant privileges and controlled the lives of the tenant farmers living on their land.

The theory is that the Roanoke settlers integrated with the Croatoan tribe after John White found the deserted settlement with the word "Croatoan" carved into a tree, indicating they moved there.

Theory on the Fate of Roanoke Settlers

One theory to explain what happened to the settlers at Roanoke revolves around the settlers integrating with the Croatoan tribe. When John White, the governor of the colony, returned to Roanoke in 1590 after an extended absence, he found the settlement abandoned with no sign of struggle, just the word "Croatoan" carved into a tree. This led to speculation that the settlers moved to live with the Croatoan tribe, possibly due to lack of supplies or other hardships. Despite the attempts by White and later explorers to locate them, their fate remained a mystery after White's return to England and still intrigues historians to this day.

Answer:

The answer is B

Explanation:

The colonists became landowners and gained political status. The colonists had come from nations (mostly England) where people had almost no chance of gaining land of their own. Political status in England was tied to landownership. As colonists acquired land in America, they were able to vote and have a voice in their government, gaining them political status. Colonists were able to participate in the government, rather than being subjected to an aristocracy. Many more citizens in the colonies had voting rights than the average citizen of England. Colonists became very concerned about the idea of property rights, and it became important to colonists to protect their own property, as well as their neighbors’, from potential government interference. In addition, protection of property rights encouraged free enterprise. The colonists were free to work the land and begin businesses without fear of the government seizing the results of their labor.
