So, imagine you had some substance in a bowl. The bowl has a little wall going through the middle, with no openings or anything.
On one side of the wall, there are 100 molecules of the supstance. On the other, there are 10 molecules.
Now, imagine that you make an opening in that little wall that separates the substance into two parts.
Normally, the 100 molecules would start pouring into the part with 10 molecules, or “go down the concentration gradient”, which means going from the part with higher concentration into lower until they are equal.
Going /against/ the concentration gradient is just the opposite — if the 10 molecules went into the side with 100, which takes energy to do.

In two or three paragraphs, compare and contrast the points of view of Wilson, Clemenceau, and Lloyd George at the Paris Peace C

Agata [3.3K]

Here is what i wrote for my essay:

World War I was settled by the victors at the Paris Peace Conference in 1919. The “Big Four,” who made all the major decisions, were President Woodrow Wilson of the United States, Prime Minister David Lloyd George of Great Britain, George Clemenceau of France, and of least importance, Italian Prime Minister Vittorio Orlando. Each major power had its own agenda coming to the Conference and not every aim was represented in the final treaties.

Wilson, Clemenceau, and Lloyd George all had different points of view at the Paris Peace Conference. For instance, lloyd George of Britain wanted to build a postwar Britain "fit for heroes". British aims at the conference were focused on securing France, settling territorial disputes, and maintaining their colonial holdings. Clemenceau of France wanted to weaken Germany so it could never threaten France. Having witnessed two German attacks on French soil in the last 40 years, France’s main concern was to ensure Germany would not be able to attack them again, so they pushed to weaken Germany militarily, strategically, and economically. Wilson of the U.S. wanted "peace without victory" with his fourteen points. The Americans’ vision was set out in Wilson’s Fourteen Points, which emphasized free trade, self-determination, and the founding of a League of Nations to support territorial and political independence of member nations.
