Answer:1) Under the Articles there was only a unicameral legislature so that there was no separation of powers.
2) The central government under the Articles was too weak since the majority of the power rested with the states.
3) Congress, under the Articles, did not have the power to tax which meant that they could never put their finances in order.
4) In order to change or amend the Articles, unanimous approval of the states was required which essentially meant that changes to the Articles were impossible.
5) For any major laws to pass they had to be approved by 9 or the 13 states which proved difficult to do so that even the normal business of running a government was difficult.
Explanation:
easy
On October 18, 1898, American troops fighting in the Spanish-American War raised the United States flag in Puerto Rico formalizing U.S. control of the former Spanish colony. General Nelson A. Miles had landed approximately 3,500 U.S. troops on the island on July 25. On August 12, Spain and the United States agreed to an armistice; on September 13, the Protocol of Peace was ratified; and on December 10, the Treaty of Paris was signed, ending the Spanish-American War.
So first off tell your teacher that the United States does not have a Democracy, it is the Federal Republic and never was a True Democracy, and that the main difference between a Democracy and the Federal Republic is that Democracy is led solely by the people unanimously voting for laws directly but the Federal Republic ( in layman's terms ) people unanimously vote for the group who gets to vote for the big decisions. Ie Electoral college. However please note that I am no expert and this is highly oversimplified.
However, If they don't accept that as a proper answer then say that it limits some of the things that may need to happen if a large enough group decides that it is unnecessary provided they are in the correct position to push against these things. Ie a war that we are currently not involved in but could become a major problem for us, say a choice is being made whether or not to engage in war a majority group in a big office somewhere in D.C. would be able to come to a decision for or against that action even if it's a choice that ends up being wrong.

Each enzyme has an "active site". The active site of each enzyme is unique in terms of 3D structure. Each unique active site can be thought of as a 3D surface that is able to bind only a single unique substrate or set of substrates, and it is the shape of the active site that is responsible for each enzyme's substrate selectivity. Most enzymes actually use the same or nearly the same, mechanisms of action; most commonly simple acid-base chemistry is used to catalyse reactions.
It may be difficult to understand, but enzyme active sites are actually thought to bind the "transition state" of the substrate. The transition state may be thought of as a state where the structure of the substrate is literally stretched to be somewhere between the orginal substrate structure, and the structure of the product of the enzyme catalyzed reaction. In other words, the enzyme can be thought of as "pulling" the substrate into a product. In this way, the enzyme lowers the energy required to pass the "transition" state, and accelerates the reaction of substrate to product.
Thus, the structure of the enzyme imparts both its substrate specificity (because only certain substrates will fit into the active site), and its activity (because in binding the substrate, the enzyme lowers the transition energy required for the substrate to form product).
Hope this helped, despite my rambling.
