Males are heavier than females; males weigh 794 to 1,323 pounds (360 to 600 kilograms), while females weigh 595 to 882 pounds (270 to 400 kg), according to the National Museum of Natural History. Moose have short tails, a hump on their shoulders and large ears that can rotate to give them stereophonic hearing.
The Effect of pH on Enzyme Activity. pH is a measure of the concentration of hydrogen ions in a solution. The higher the hydrogen ion concentration, the lower the pH. Most. enzymes function efficiently over a narrow pH range. A change in pH. above or below this range reduces the rate of enzyme reaction. considerably.
The soil pH value is a measure of soil acidity or alkalinity. Soil pH directly affects nutrient availability. The pH scale ranges from 0 to 14, with 7 as neutral. Numbers less than 7 indicate acidity while numbers greater than 7 indicate alkalinity.he pH value of soil is one of a number of environmental conditions that affects the quality of plant growth. The soil pH value directly affects nutrient availability. Plants thrive best in different soil pH ranges. Azaleas, rhododendrons, blueberries and conifers thrive best in acid soils (pH 5.0 to 5.5).
