So the liquid doesn't damage the lenses
The microscope has two systems of lenses: the ocular lens into which the observer looks; and objective lenses placed directly above the object being observed.

The 'object lens' in a compound microscope is closest to the object being examined.
Not really. An electron microscope requires that the specimen be placed in a vacuum for viewing. It would most certainly kill any living creature placed inside it. No, the specimen being viewed is incapible of life after being placed into the slit.

i need the answer of this question urgently
it has to be placed in alcohol first because lipids are soluble in alcohol but not in water.
True
For a scanning electron microscope, the most commonly used type of EM, there is no need to do anything other than stick it to an electrically conducting pad. If the sample is particularly insulating, it may be worth coating it with a very thin gold layer to prevent the specimen from charging up with electrons from the beam (this would blur the image) For a transmission electron microscope, the specimen is most commonly encased in epoxy resin before being sliced into thin enough slices that the electron beam can pass through. The sample is then placed on a fine copper grid before being placed in the microscope.

The sausage rolls being placed seam side down will make them look nicer. By the seam being placed down before baking, the roll itself will maintain its desired shape through the baking process. If the seam were placed facing upward, then the roll will puff up with the form being deformed.

Magnifies the object being observed through the microscope. The magnification of the lens being used will determine how closely the object can be viewed.
