It is a prehistoric bug that is mostly closely related to the arachnids of today. I lacks a spinneret though. It is one of the first trigonotarbids to ever be described. (It looks like a spiky tick. Seriously)
Answer:
light microscopy allows the visualization of dynamic processes in living cells light
Explanation:
Light microscopy has a biggest advantage over electron microscopy because it all the visualisation or ability to observe living cells and biological activity such as the uptake of food, cell division and movement. Light microscopy can be use in-vivo staining techniques to visualise the uptake of colored pigments by the cells which cannot be observed with electron microscopy because in electron microscopy the element must be fixed, dehydrated or dead before been visualised . Electron microscope cannot observe living cells and can only observe dead or dry specimens so that electrons can pass through the specimen to be able to observe.
