Your psychrometer indicates that the relative humidity is very low. Rain probably won't occur.

A psychrometer consist of two thermometers - a dry bulb thermometer that is used to measure the temperature by being exposed to the air  and a wet bulb thermometer that measures the temperature by having the bulb dipped in a liquid. This instrument measures the relative humidity in the atmosphere through the use of these two thermometers.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
