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.
Here are some things that can affect enzyme activity: 1  Temperature - The temperature can affect the reaction rate. The higher the temperature, the faster the reaction will occur. 2  pH - In many cases the pH level, or acidity, of the environment around the enzyme and substrate can affect the reaction rate.
