Answer:
If the duration of life on Earth was on a scale of 20,000 days, the human species would be present in the Earth for approximately 9 days.
Explanation:
We can't be sure about the exactly age of the Earth, but we can base our calculus in a number between 4400 and 4600 million years, because the most accepted researches shows numbers in this span of time. We can take the average of those limits: 4500 million years.
On another hand the presence in the Earth of human species has not a precise date because of the it does not have a precise date for two main reasons, the scientific evidence does not include all the human species that existed on Earth but it is a very incomplete evidence and besides being an evolutionary phenomenon it is not easy to determine from what moment We can consider that a species belongs to the human race or not. In any case, we take the approximate date of the scientific evidence of the existence of human species in an age of 2 million years.
With both numbers we can calculate the proportion in the scale of 20 thousand years throw the following formula:
PHS = 20000 years . 2 million years / 4500 million years = 8.9 years
PHS: Presence of Human Species
Explanation:
Site is the exact location of a city, you can find it on a map. The situation of a city relates to its surrounding features, both human-made and natural.

Answer:
It's important to understand that the U.S. we have a "republic" and it's a representative democracy. The citizens have a say in the government, however we have to vote on representatives that have the same ideas as us. Unlike ancient Greece, e.g Athenians, who voted directly on the law without having to go through representatives.
Explanation:
Each year 500 names were chosen from all the citizens of ancient Athens. Those 500 citizens had to actively serve in the government for one year. During that year, they were responsible for making new laws and controlled all parts of the political process. When a new law was proposed, all the citizens of Athens had the opportunity to vote on it. To vote, citizens had to attend the assembly on the day the vote took place. This form of government is called direct democracy.
The United States has a representative democracy. Representative democracy is a government in which citizens vote for representatives who create and change laws that govern the people rather than getting to vote directly on the laws themselves.
