Frogs have webbed feet to help them swim- they would have no need of keratin (the substance in nails).
So far as I know, this would be called an electron microscope.
You would use a microscope
A microscope that uses electrons to examine a specimen is called a transmission electron microscope (TEM). It has a higher magnification and resolution compared to light microscopes, allowing for detailed viewing of subcellular structures and particles.
Someone who wanted to examine tiny organisms would have to use a microscope.
i think it is the light microscope or the dissecting microscope the technician will use only one objective lense x2
They don't swim like fish but use their wings as they would in the air - they fly though the water.
A scanning electron microscope (SEM) would be used to examine the surface details of a cell. It provides high-resolution 3D images of the cell surface by scanning it with a focused beam of electrons.
A microscope is typically used in science classes, such as biology, chemistry, or physics, to magnify and examine small objects and organisms that are not visible to the naked eye.
If you could examine a mineral with a powerful microscope that reveals atoms and ions, you would see the arrangement of individual atoms within the crystal lattice structure of the mineral. This would give you insight into the bonding between atoms, the types of elements present, and the overall crystal morphology of the mineral at a microscopic level.
That would be a Transmission Electron Microscope (TEM). It uses a beam of electrons to pass through a thin specimen, creating a magnified image that allows for detailed examination at the atomic level.
A light microscope would be suitable to observe a splinter in the finger as it provides enough magnification and resolution to see small objects like splinters. Additionally, a dissecting microscope could also be used for larger splinters to examine them in more detail.
