An electron microscope, particularly a transmission electron microscope, can be used to visualize DNA as its electrons have a shorter wavelength enabling higher resolution. For botulinum toxin, a scanning electron microscope can also be used to visualize its structure due to its high magnification capabilities.
An electron microscope has the capability to magnify up to 500,000 times, providing highly detailed images of specimens at the molecular level. This type of microscope uses a beam of electrons to visualize the sample, allowing for incredibly high resolution and magnification.
An electron microscope allows us to see cell organelles. It uses a beam of electrons to create a detailed image with high resolution, making it possible to visualize structures at the subcellular level.
A light microscope, specifically a compound microscope, is commonly used to view Staphylococcus aureus. This type of microscope uses visible light and multiple lenses to magnify and visualize the bacteria at a cellular level. Staining techniques can also be applied to enhance contrast and aid in identification.
A variety of different microscopes can be used to visualize the sub-cellular structures in a cell. They can be:a bright field microscope (simple in construction but not very accurate)A phase contrast microscope (gives a better idea of the three dimensional orientation of the sub-cellular structures)A fluorescent microscope (the most specific type of scope. This allows one to see very specific structures like the individual strands of actin that make up the cytoskeleton)
a scanning probe microscope
You would use a light microscope to see the parts of a cell. This type of microscope uses light to magnify the structures within a cell, allowing you to visualize organelles such as the nucleus, mitochondria, and cell membrane.

For example a microscope.
A light microscope would typically be used to look at a blood sample. This type of microscope has sufficient magnification and resolution to visualize blood cells such as red blood cells, white blood cells, and platelets.
An electron microscope has the capability to magnify up to 500,000 times, providing highly detailed images of specimens at the molecular level. This type of microscope uses a beam of electrons to visualize the sample, allowing for incredibly high resolution and magnification.
A compound microscope typically uses light energy, specifically visible light, to illuminate the sample being observed. This light passes through the lenses of the microscope to magnify and visualize the specimen.
Scientists use a scanning tunneling microscope (STM) or an atomic force microscope (AFM) to visualize atoms. These microscopes operate at the nanoscale level and rely on detecting the tiny forces that exist between the microscope tip and the atoms to create detailed images of atomic structures.

Scientists would typically use an electron microscope to determine if a bacteria has a virus. Electron microscopes have high magnification and resolution capabilities, allowing them to visualize viruses, which are smaller than bacteria. This type of microscope is crucial for studying the ultrastructural details of viruses interacting with bacteria.
Viruses are best seen through an electron microscope because of their extremely small size. Electron microscopes use a beam of electrons to magnify objects, allowing for resolution of structures as small as a few nanometers, which is necessary to visualize viruses. Light microscopes are not powerful enough to visualize structures at this level of detail.
