PLEASE HELP ME I NEED ASAP.<br> Complete the following table on the different types of microscopes.
Dmitrij [34]

Answer:

A compound light microscope is a microscope with more than one lens and its own light source. In this type of microscope, there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen.

The scanning electron microscope (SEM) produces images by scanning the sample with a high-energy beam of electrons. As the electrons interact with the sample, they produce secondary electrons, backscattered electrons, and characteristic X-rays.

garri49 [273]

A brain tumor is likely located in the following parts of the brain if it is causing clinical manifestations of headache, nausea, projectile vomiting, and mental changes:

  • frontal lobe
  • intra-axial or intracranial cavity lesions within the parenchyma
  • extra-axial or outside brain tissue but within the cranium

Other clinical manifestations include alterations in sensory function, alterations in motor function, papilledema, and frequent visual disturbances.

Frontal lobe tumors also grow to a large size and cause increased intracranial pressure (ICP) while tumors within the intracranial cavity are fixed and can also cause ICP.


The image attached here shows where tumors are located if it's at the front lobe, intra-axial, and extra-axial.
