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.

Why enzyme activity is affected by pH. by Bhav Patel Â· October 10, 2014. Why enzyme activity is affected by pH. A pH is the measure of the concentration of hydrogen ions, H+ with their values ranging from 1 -14. pH 7 is said to be neutral, any value below this is said to be acidic and values above are alkaline.y doing this, it interferes with the binding of the substrate to the active site and it therefore changes the rate of activity of the enzyme â the rate of an enzyme controlled reaction). Every enzyme has their own optimum pHs; the pH where the rate of the enzyme controlled reaction is at its highest.
