Answer:
The United States developed and used the first nuke in WW2
Explanation:
America dropped the bombs on the Japanese cities of Hiroshima and Nagasaki. Some people say it was inhumane to decimate entire cities in a war. However, America would not have entered the war in the first place if they were not provoked by the unjustified obliteration of a US Navy fleet and base that occurred a few years prior at Pearl Harbor. The nuclear bombs created an instant submission of the opposing forces and helped bring an end to WW2. This did, however, lead to the cold war era between the world superpowers.
Answer:
Because of survival instinct.
Explanation:
Before Humans became a social creature, they rely on their power to survive in the harsh environment. They fend for themselves, make their own shelter, fight off all the dangerous alone, etc.
Of course, many of them fail and died since there's only so much that a single human can do.
Knowing this, they try to combine their abilities and form groups to survive in the harsh environment. They soon realized that forming a group dramatically increase the chance of their survival since they can rely on other members to cover each other's weaknesses.
This is why humans started too transformed into a social creature.
Answer:
The dependent variable is the amount of money each group chooses to donate.
Explanation:
A simple way to be able to identify the dependent variable from the independent variable is to observe which element of the research is stimulating something to happen and what this "something" is. This is because the independent variable is the one that has the power to influence the occurrence of "something." This "something" is the dependent variable that occurs when it is influenced by the independent variable.
In the case of the above experiment, we can see that researchers want to research whether looking at pictures of poor children is able to influence the amount of money a person would donate to a charity. Thus, we can affirm that the picture of poor children is the independent variable of the experiment, while the amount of money donated by each group is the dependent variable.
