In an experimental investigation,what is the variable that the researcher changes or manipulates in order to see its effects is called?
Answer:
Explanation:
La investigación experimental es cualquier investigación realizada con un enfoque científico, donde un conjunto de variables se mantienen constantes, mientras que el otro conjunto de variables se miden como sujeto del experimento.
La investigación experimental es uno de los métodos de investigación cuantitativa principales.
El ejemplo más simple de una investigación experimental es una prueba de laboratorio. Siempre que la investigación se realice bajo condiciones científicamente aceptables, se califica como una investigación experimental.
Una verdadera investigación experimental se considera exitosa sólo cuando el investigador confirma que un cambio en la variable dependiente se debe a la manipulación de la variable independiente.
Es importante para una investigación experimental establecer la causa y el efecto de un fenómeno, lo que significa que debe ser claro que los efectos observados en un experimento se deben a la causa.
Como es natural, puede ser que los eventos que ocurran sean confusos y no permitan a los investigadores establecer conclusiones fácilmente.
Por ejemplo, un estudiante de cardiología realiza una investigación para comprender el efecto de los alimentos en el colesterol y resulta que la mayoría de los pacientes con problemas de corazón no son vegetarianos ni tienen diabetes, es porque comen carne (supongamos). Este último puede ser un aspecto (causa) que puede provocar un ataque cardiaco (efecto).

1.How does the government of Charles
Towne exemplify the move toward self-rule?
2. How does South Carolina move to a more
representative form of government?
Answer and Explanation:
1. Charles Town established a provincial government in a colonial territory. This exemplified and showed the foundations of self-government, which was still new in colonial America. With the provincial government, the citizens of Charles Town were able to choose popular representatives to compose a type of legislative chamber.
2. South Carolina has shifted to a more representative form of government after the colonists were exhausted by the British irresponsibility of government. The British government had little experience in this type of enterprise and ended up failing with the control and legislation of the colonies. This created injustices and abuse of power in an extreme way, causing the colonists to enter into a rebellion against England, demanding government and administrative control of their colony, which allowed South Carolina to have a representative government, where the representatives were chosen by the people.

In regards to the Law of Supply, Price and Quantity Supplies have A direct relationship (if price goes up quantity supplied goes up too) An indirect relationship (if price goes up quantity supplied goes down) A varying relationship (if price goes up it depends on the specific situation to determine if quantity supplied goes up or down) No relationship because it is price and supply (shouldn't be quantity supplied)
Answer:
A direct relationship (if price goes up quantity supplied goes up too)
Explanation:
The law of supply states that as the price of a good increases so does the quantity the supplier is willing to provide to the consumer. Also as price decreases the quantity the supplier is willing to provide reduces all things being equal.
Increase in price results in an increased profit for the supplier so they are motivated to supply more of the good.
Therefore there is a direct relationship between the price and quantity supplied of a good.
For example if the price of a good is $10 and the supplier incurs cost of $7 in producing it he will make a profit of $3. An increase in price to $20 will increase his profit to $13.
This will motivate him to increase production.

If the government under the Articles of Confederation was so ineffective, why were there no changes made to improve it?
The national military would not allow changes to the Articles.
There was no method by which changes to the Articles could be made.
All the states had to agree in order to pass an amendment to the Articles.
A court would have to approve any change to the Articles, and there was no court.
If the government established by the Articles of Confederation was so inefficient, no adjustments were made to enhance it, since there was no way to change the Articles. Thus, option B is correct.
What is government?A government is a legal entity that is made by the reforms or the method that are being given in the constitution. There are various groups and departments that are made, which usually control the policies and actions of their departments.
