What does an Independent variable, dependent variable, and control variable mean??
Answers
Final answer:
In an experimental study, the independent variable is manipulated by the researcher to create change, while the dependent variable is measured to see the effects of that change. Control variables are constants that help ensure the integrity of the experiment by keeping all other potential influences equal.
Explanation:
Differences Between Independent and Dependent Variables
In an experimental study, two types of variables play critical roles: the independent variable and the dependent variable. The independent variable is the factor that the experimenter manipulates. It’s considered the 'driver' variable because it creates change in the experiment. For example, if you’re testing how fertilizer affects plant growth, the type of fertilizer or its presence would be the independent variable.
The dependent variable is the 'receiving' variable that changes as a result of the independent variable’s influence. It’s what the researcher measures to see the effects of the independent variable. In the fertilizer example, the dependent variable is plant growth.
Number of Dependent Variables in an Experiment
Typically, you would want to focus on one dependent variable in an experiment to ensure that you can attribute changes in the dependent variable directly to the manipulation of the independent variable.
Importance of Control Variables
Control variables are constant factors in an experiment that are not changed or vary during the investigation. They serve to ensure that the only variable affecting the outcome is the independent variable. This helps in maintaining the experiment’s integrity and ensuring that the results are due to the independent variable only and not other confounding factors.
For instance, when examining plant growth, control variables could include soil quality, water levels, and sunlight exposure because these factors could also affect plant growth.

Answer:
The main responsibility of the Transportation Security Administration is to provide police protection for airline passengers.
Explanation:
The Transportation Security Administration (TSA) is an American federal agency within the Department of Homeland Security, serving public safety in transportation. It was created under the Aviation and Transportation Security Act 2001 and endorsed by the 107th Congress. It belonged until the end of February 2003 to the Department of Transport. There are currently 43,000 employees here whose transportation officers are armed with police powers.
The task of the TSA is the maintenance of public safety on highways, railways of all kinds, ports (sometimes also abroad) and 450 airports nationwide (the latter to a small extent by private security services as part of a so-called screening partnership program). The range of tasks includes activities in the fight against terrorism, illegal immigration, prohibited items and much more.
How did the south solve the problem of reconstruction after the civil war?
Answers
Final answer:
The South aimed to solve the problem of reconstruction after the Civil War through efforts like the Thirteenth Amendment, which abolished slavery, and initiatives to diversify the Southern economy. However, challenges such as resistance from Southern whites and the rise of Jim Crow laws made success limited.
Explanation:
How did the South solve the problem of reconstruction after the Civil War? The period following the Civil War, known as Reconstruction (1865-1877), aimed to reintegrate the former Confederate states into the Union, abolish slavery, and rebuild the Southern economy and society.
This era saw the implementation of the Thirteenth Amendment, which outlawed slavery, and efforts to promote the rights of newly freed African Americans. Despite intentions, Reconstruction faced challenges, including resistance from Southern whites, leading to the rise of sharecropping and the eventual imposition of Jim Crow laws.
Some believed that establishing a "New South" with a diversified economy and upgraded agriculture could solve these challenges. However, the Reconstruction period ended with mixed results, leading to a continued struggle for African American rights and Southern economic development.

How many people have been killed by the kkk?
Answers
Unlike the new terrorist groups out today, the KKK hid behind bed sheets for fear of discovery. They didn't always take credit for their murders. Also consider that they didn't have sophisticated ways to publicize the terroristic acts like we do now. Even if they did, it would be a stretch to assume they'd be smart enough to know how to use them.
Plus, the era they were in full power was also during a time when the government didn't care about black lives (even worse than today, if you can imagine that). So they made little effort to track these things.
And you certainly couldn't expect the KKK to keep an accurate count once the number got past 10. According to the Huffington Post, a recent study puts the number at 3960. That's just for Blacks. Keep in mind that they also hated Jews, Catholics, Republicans (before the switch) and anything intelligent. So I expect the number to be at least 20% higher with everyone included. But this number still doesn't include the killings that we can't prove were done by the kkk. The cop murders where the cop was a secret kkk member
The FBI murders that never made sense
The random poisoning here and there

What major legal and political changes led to the rise of constitutional government in the west?
Answers
The major legal and political changes that contributes to the rise of constitutional government in the west is most likely because of consent in which people have given the rights and the equality of which all people are treated equal. This had brought up big chances in their society.
Answer:
The major political changes came from both the american revolution and the french revolution. The american revolution was inspired by the ideas of liberalism developed by thinkers such as John Locke and Montesquieu. This ideas held that the invidividual is more important than the collective, and that every person has rights given by god, which came to be known as human rights. Finally, liberals opposed monarchy and instead favored republicanism, which means that the government should be elected by its people, and could be removed from power in anytime in case it does not satisfy its people's needs.
These ideas inspired the development of constitutions. A constitution is the supreme law of the state, form which all other laws are derived. The first constitution was the United Sates constitution, which defended liberal principles such as freedom of speech, freedom of religion and freedom of assembly. With time, intellectuals in other european countries took insipiration from the US constitution and began to introduce changes in their countries of origin.

Ivan IV, also known as Ivan the Terrible, was the first to declare himself Tsar of all Russias and annexed various khanates, but he did not create St. Petersburg, the serfs, socialism, or the Eastern Orthodox Church.
Explanation:Ivan IV and His Legacy
Ivan IV, known as Ivan the Terrible, is credited with the annexation of various khanates such as Kazan, Astrakhan, and Siberia, and is famous for his harsh rule and establishment of a centralized Russian state. However, to answer the question more directly, he is not credited with any of the mentioned achievements such as creating St. Petersburg, the class known as serfs, socialism, or the Eastern Orthodox Church. The establishment of St. Petersburg was achieved under the rule of Czar Peter the Great in the 18th century, the class of serfs existed in Russia prior to Ivan IV but was later emancipated by Tsar Alexander II in 1861. Socialism was a concept that was developed much later than Ivan IV's time, and the Eastern Orthodox Church had been a significant part of Russian life for centuries before Ivan IV became Tsar.

Facts about Gorge Washington childhood/early life
Answers
He was born February 22, 1732 to Augustine Washington and his second wife, Mary Ball Washington. At the time of his birth, George had two half-brothers from his father’s first wife, and later, five additional siblings were born after George.
George’s mother was a troubled person, and this affected her children. Mary Ball Washington was the child of a marriage between a wealthy gentleman who married a family housemaid who had no education. It was a legitimate marriage, so Mary eventually inherited land, slaves, and money from her father, but she was ill-prepared to step into the role of mother and mistress of a successful household. Biographers report that she was defensive and over-protective of her children to the point that their childhood may have been quite stressful. For example, other children in the area reached an age when they were considered old enough to play by the river, but Mary never gave her children this type of freedom, fearing they might drown.
During the years when George’s father was alive, the family lived at Ferry Farm near Fredericksburg. When Augustine died in 1743, he left the family 10,000 acres and 50 slaves. George was 11 at the time and went to live with his older half-brother Lawrence who was 14 years his senior.

What were the main achievements of the glorious revolution?
Answers
The Glorious Revolution led to the 1689 Bill of Rights establishing a constitutional monarchy, limited the monarch's powers, and laid the groundwork for modern democracy. It also defined the relationship between the monarchy and Parliament, promoting rights like trial by jury and freedom of speech.
Explanation:The Glorious Revolution marked a significant turning point in English history, resulting in the establishment of a constitutional monarchy and solidifying the powers of the Parliament over the monarchy. One of the main achievements of the Glorious Revolution was the acceptance of the 1689 Bill of Rights, which not only limited the powers of the king but also laid down fundamental rights for English citizens such as the right to freedom of speech, regular elections, and trial by jury. Another major outcome was defining the permanent relationship between monarchy and Parliament, which moved England towards a system of government where laws and policies required the consent of the governed, rather than being decreed by the sovereign's absolute power.
Although the Glorious Revolution didn't establish a full democracy, as voting rights were still limited to the nobility and gentry, the Bill of Rights did introduce principles of equal treatment under the law and set a foundation for future democratic developments. Additionally, the revolution had far-reaching effects not just in England, but across the British colonies as well, influencing their own governance and pursuit of liberty.
