Question: What is melanoma and is it life-threatening? Answer: Melanoma is a type of skin cancer and is considered to be the most dangerous form of the disease. Although less commonly diagnosed than other types of skin cancer, melanoma accounts for over 75% of skin cancer deaths. Melanoma develops in cells called melanocytes that are found in the lower part of the epidermis, the outer layer of your skin. Melanocytes are cells that are responsible for creating skin pigmentation, or melanin. Melanin is what gives our skin its natural hue.
In the 18th century only the American revolution produced a sustainable democracy. During the 19th century monarchists fought a prolonged rearguard action against democratic forces. In the first half of the 20th century nascent democracies collapsed in Germany, Spain and Italy. By 1941 there were only 11 democracies left, and Franklin Roosevelt worried that it might not be possible to shield âthe great flame of democracy from the blackout of barbarismâ.
In a republic, instead of voting directly about what they want to do, as in a democracy, people instead vote for people to represent them, and those people decide what to do.The first republic was the Roman Republic, which was founded about 509 BC, just about the same time as the first democracy in Athens.The rules about who could vote were about the same as in Athens too: slaves couldn't vote, and neither could women, or children, or men who were not citizens.he republic was a lot more efficient than the democracy, because most men who could vote only needed to vote in the big elections, and the rest of the time they could be at work. Only the Senators, the elected representatives, had to be voting all the time.
