Answer #1

True
explanation:The scanning electron microscopy helps in viewing the surface of unsectioned specimens.
Electrons pass through the entire specimen.The sample is fixed dried and coated with a thin layer of platinum or any heavy metal,metal is deposited uniformly and the electron beam inside microscope scans the sampleand as the number of secondary electrons produced by any one point on the sample depends on the angle of electron beam in relation to the surface thus producing a 3D image so we say it visualises metal cast of actual specimen.
