Because the bubbles will destroy the electrons
Bubbles in microscope specimens can distort the image and make it difficult to see the sample clearly. They can also interfere with focusing and magnification, impacting the accuracy of observations. Proper sample preparation techniques, such as using mounting media carefully and avoiding air bubbles, can help mitigate this issue.
Both the compound microscope and dissecting microscope use lenses to magnify objects. They both have adjustable focus and are used for viewing specimens in detail, but the compound microscope is more powerful and used for viewing smaller specimens at a cellular level, while the dissecting microscope is used for larger specimens at a lower magnification.
The things you look at under a microscope are called specimens. These specimens can be a variety of materials, such as cells, tissues, or microorganisms.
No, a Scanning Electron Microscope (SEM) cannot be used on living specimens because the high vacuum and electron beam used in an SEM would quickly kill the specimen. For observing living specimens, a different type of microscope, such as an optical microscope or a specially designed environmental SEM, should be used.

Taking pictures of specimens.
A microscope is a pointed object used to examine specimens closely.
The objective lenses on a microscope collects light and brings the specimens into focus.

The type of microscope that focuses beams of electrons on specimens is the electron microscope. It uses a beam of electrons to create a highly magnified image of the specimen, allowing for detailed visualization of structures at the nanoscale.
