The wet bulb depression is the difference between the dry-bulb temperature and the wet-bulb temperature. It is measured by a psychrometer . If there is 100% humidity, dry-bulb and wet-bulb temperatures are identical, making the wet-bulb depression equal to zero in such conditions.
(In short; the difference between the temperature of a dry bulb and wet bulb.)
There are 5 major climate types worldwide.
I am pretty sure the answer is increase and increase. Because enzymes are affected by changes in pH. The most favorable pH value - the point where the enzyme is most active - is known as the optimum pH. Extremely high or low pH values generally result in complete loss of activity for most enzymes.
