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).

Where did the british empire expand to and why did they choose these places?
lutik1710 [3]

Answer:

The British Empire was composed of the dominions, colonies, protectorates, mandates, and other territories ruled or administered by the United Kingdom and its predecessor states. It began with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. At its height it was the largest empire in history and, for over a century, was the foremost global power.[1] By 1913 the British Empire held sway over 412 million people, 23 per cent of the world population at the time,[2] and by 1920 it covered 35,500,000 km2 (13,700,000 sq mi),[3] 24 percent of the Earth's total land area. As a result, its constitutional, legal, linguistic, and cultural legacy is widespread. At the peak of its power, it was described as "the empire on which the sun never sets", as the sun was always shining on at least one of its territories.[4]

Philadelphia, Pennsylvania hosted the Constitutional Convention from May 14 to September 17, 1787. Choosing America's future government was the main goal of the event. Many of the delegates had considerably more ambitious ambitions than the ostensible purpose of the Convention, which was to amend the current Articles of Confederation.

Write a 250-word essay that argues your opinion about the constitutional convention.

In May 1787, delegates from every state—aside from Rhode Island—met in Philadelphia, Pennsylvania, for a convention. The Articles of Confederation were to be rejected in favor of a new constitution, it was agreed at this gathering, which became known as the Constitutional Convention. In addition to completely rejecting the Articles of Confederation, the fifty-five delegates who gathered in Philadelphia between May 25 and September 17, 1787, would draft the first written constitution for a country in the history of the globe. The Constitution established unique governmental principles and procedures such as checks and balances, the division of powers among the branches, and the definition of those powers. The amendment process also transformed the Constitution into a living document that could be altered with sufficient popular support and state ratification. The government can first be constrained by the constitution by identifying or enumerating its powers. No authority not expressly granted or listed to the government may be assumed by it. Second, it is possible to split the executive, legislative, and judicial branches of the government. Two Congressional legislative bodies were established by the Great Compromise. V!rginia (big state) and New Jersey (little state) plans were united in the agreement, which is also known as the Sherman Compromise or the Connecticut Compromise. Roger Sherman, a delegate from Connecticut, advocated a "bicameral" or two-chambered Congress, with each state receiving two seats in the upper chamber and a number of representatives in the lower chamber (the House) according to its population (the Senate).
