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
Someone who wanted to examine tiny organisms would have to 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.
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 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.
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.
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.
The platypus has webbed feet to help it when it swims. It has retractable webbing between the claws on its front legs and hind legs. The claws are needed for when the platypus digs its burrow, but the webbing would be torn by the digging; hence it is retractable. Similarly, because the sea otter and beaver are semi-aquatic mammals, they also have webbed feet. Many waterbirds, such as ducks, geese, swans, pelicans, storks and a variety of waterfowl have webbed feet.
