No, electron microscopes cannot generally be used to observe living cells. The preparation process for electron microscopy involves dehydration and vacuum conditions that are incompatible with maintaining living cells. Electron microscopes use electron beams instead of light to achieve much higher resolution images than light microscopes. However, the sample preparation for electron microscopy involves fixing, […]

Staphylococcus bacteria appear as spherical clusters or grape-like structures under a microscope. Staphylococcus, commonly known as staph, is a genus of bacteria characterized by its round shape and tendency to form clusters. When viewed under a microscope, these bacteria appear as spherical clusters resembling grapes or bunches. The name “staphylococcus” is derived from the Greek

Yes, electron microscopes are expensive. Electron microscopes are sophisticated scientific instruments that use electron beams to achieve extremely high magnification and resolution, allowing researchers to observe objects at the nanoscale. The technology and precision required in electron microscopes contribute to their high cost. These instruments often involve complex components, including electron sources, electromagnetic lenses, detectors,

Under a microscope, a kidney stone typically appears as a crystalline structure with various shapes and sizes, such as jagged edges or smooth surfaces, depending on the composition of the stone. Kidney stones are formed from accumulating substances in the urine, such as calcium, oxalate, and phosphate. These substances can crystallize and aggregate, leading to
