Answer:
Scientists must cut a thin slice of the biological sample because light from the microscope must be able to pass through that slice to form a complete image of it.
Explanation:
The microscope is an instrument designed especially to be able to appreciate very small elements and that, obviously, are almost imperceptible to human vision. In general, any microscope is composed of the following components: a source (such as an electron beam that promotes a light), a sample (on which this source acts), a receiver (in charge of receiving the information provided through the source and the sample) ) and an information processor (almost always a computer).
This sample must be cut into thin slices and these slices will be observed under the microscope. Scientists must cut a thin slice of the biological sample because light from the microscope must be able to pass through that slice to form a complete image of it.
