Ascientist want to observe the structure that joins a cell to neighboring cells. how should the scientists observe

With the help of an electron microscope.

Explanation:

A technique that helps in attaining high-resolution images of non-biological and biological specimens is known as electron microscopy. It is utilized in biomedical research to determine the complete composition of the cells, tissues, organelles, and macromolecular complexes.  

The images obtained from the electron microscope provides key knowledge regarding the structural basis of cell function and various diseases associated with the cells. Thus, if a scientist desires to see the structure, which binds a cell with the adjacent cells, he or she should use an electron microscope.
