In reality, this classification means there is a one-percent chance that such a flood could happen in any given year. Over recent decades, possibly due to global climate change, hundred-year floods have been occurring worldwide with frightening regularity. Moving water has awesome destructive power.n reality, this classification means there is a one-percent chance that such a flood could happen in any given year.

Answered by The Community. Making the world better, one answer at a time. The aspect of a chemical reaction that is affected by enzymes is rate. The four main groups of carbon based molecules are carbohydrates, lipids, proteins, and nucleic acids.
They are similar to other chemical catalysts in many ways: 1  Enzymes and chemical catalysts both affect the rate but not the equilibrium constant of a chemical reaction. 2  Enzymes and chemical catalysts increase the rate of a chemical reaction in both directions, forward and reverse. This principle of catalysis follows from the fact that catalysts can't change the equilibrium of a reaction.
