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.
PH changes affect the structure of an enzyme molecule and therefore. affect its ability to bind with its substrate molecules. Changes in pH. affect the ionic bonds and hydrogen bonds that hold the enzyme. together, which naturally affects the rate of reaction of the enzyme. with the substrate.he optimum pH for most enzymes is pH7. In the body, amylase works mainly in the small intestines, where the. acidity from the stomach has been neutralised by the hydrogencarbonate. ions in the pancreatic juices secreted by the pancreas.
