When thereâs not enough of these hormones, your body has trouble with these basic functions. That causes the symptoms of adrenal insufficiency -- fatigue, muscle weakness, low appetite, weight loss, and belly pain, among others. You can have either primary or secondary adrenal insufficiency.
In the DOM event model, there is a clear distinction between an event listener and a listener function: an event listener is an instance of a class that implements the EventListener interface, whereas a listener function is a method of that class named handleEvent().
Active listening is a structured form of listening and responding that focuses the attention on the speaker. The listener must take care to attend to the speaker fully, and then repeats, in the listener=s own words, what he or she thinks the speaker has said.
