Answer:
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.
Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions. In humans, cells differentiate early in development to become nerve cells, skin cells, muscle cells, blood cells, and other types of cells. One can easily observe the differences in these cells under a microscope. Their structure is related to their function, meaning each type of cell takes on a particular form in order to best serve its purpose. Nerve cells have appendages called dendrites and axons that connect with other nerve cells to move muscles, send signals to glands, or register sensory stimuli. Outer skin cells form flattened stacks that protect the body from the environment. Muscle cells are slender fibers that bundle together for muscle contraction.

That seems like such common sense that it's hard to understand that

Nations form alliances in order to achieve goals that otherwise wouldn't be possible. For example, NATO, or the North Atlantic Treaty Organization, a coalition of countries in North America and Europe, agree to defend one another in case of attack from an outside party. This is clearly beneficial, because this intergovernmental support both makes an outside attack less probable, and if it occurs, easier to handle. Another example is NAFTA, or the North American Free Trade Agreement. Shared among Canada, the US, and Mexico, this alliance eradicated trade barriers within these countries. Another beneficial alliance, this agreement increases international trade due to lower costs and thus improves the international economy.
