Answer:

1. microscope

2. Galileo Galilei

3. Microscopes have contributed significantly in the fields of cell biology and histology where great discoveries have been made over the years. The discovery of blood cells in the human body paved the way for advanced studies in cell biology.

4. Both of these microscopes have an objective lens, which is closer to the object, and an eyepiece, which is the lens you look through. The eyepiece lens typically magnifies an object to appear ten times its actual size, while the magnification of the objective lens can vary

5.  When focusing on a slide, ALWAYS start with either the 4X or 10X objective. Once you have the object in focus, then switch to the next higher power objective. Re-focus on the image and then switch to the next highest power.

6 Since the scanning lens allows you to see a larger portion of your slide in less detail, you may need to increase your magnification. To switch to the next magnification, carefully turn the revolving nosepiece until the low power lens (10X objective) is locked in place.
