Answer:

1.false.

There are special lense tissues for this which will not scratch the lense so that  the focal power will nit be affected. Grit -free lens paper,Kimwipes or Kodak lens are ideal cleaning  materials.

2.This is also false. Microscope should be covered with dust cover, and even in the cabinet,It should never be left without am eyepiece.

3.True.

This gives he lowest magnification, which allows for wide view of the specimen in order get the specific spot to focus on.It has  magnification power  of 10x eyepiece  lens.Thus a 4x scanning objective lens therefore  gives  total magnification of 40x.

4.False,

This will break the objective lens.Fine adjustment knob should be use.This will gives the sharpest focus,using a coarse knob will crack the lens because the working distance for focusing will be too small, and suing this will damage the objective lens,

5.False,only the wet mount should be used.High power and oil lens should not be used as this will reduce the efficiency of the microscope.
