The high number of people from Latin America migrating to America is mainly to find new economic opportunities.
Explanation:
pThe United States is the biggest economy in the world, thus it is the most attractive country in the world for people to migrate in. Even though there are migrants from everywhere in the world, the biggest percentage of them comes from Latin American countries. Some of the people from Latin America migrate legally, while some do it illegally and after ending up in the country try to find ways to become legal citizens.
There are multiple reasons why people from this region migrate in mass numbers to the United States but the primary one is of economic nature. The majority of the people in Latin America live in poor conditions, so in order to get a better life and better economic opportunities they migrate to the United States where they can find jobs much more easily and have a better life.
The main difference in the process of waste removal between unicellular and multicellular organisms is the fact that unicellular organisms rely on only their membrane and organelles, the whole process is in inside the cytoplasm of the cell and once waste is formed, it is "packed" in special sacs called vacuoles and then, through the process of exocytosis they are being left out of the cell. On the other hand, multicellular organisms most often have specific organs that are in charge of the process of digestion, absorption and excretion or removal of waste.
