Answer
Hi Shuvo
 1.With a wet mount a drop of water with organisms is place don the slide with a cover slip With the hanging drop no cover slip is used and the slide is inverted over a depression slide. Hanging drops are not used very much any more
 2. Moist and dry heat are self explanatory. Moist heat involves a higher humidity
3.Microbiology is important in all the areas mentioned but more involved with health studies
