Question

1. what is the size of the nucleus in micrometers? 6. what is the size of the cell in micrometers? 7. what is the size of the field of view in micrometers? in millimeters? 8. describe the changes in the field of view and the amount of available light when going from low to high power using the compound microscope.

Explanation:

Step1: Identify given measurement

The scale shows 1 mm for the field - of - view.

Step2: Convert mm to micrometers

Since 1 mm = 1000 micrometers ($1\mathrm{mm}=1000\mu\mathrm{m}$), the size of the field of view in micrometers is 1000 $\mu\mathrm{m}$ and in millimeters is 1 mm.

Step3: Explain microscope power changes

When going from low to high power using a compound microscope, the field of view decreases (you see a smaller area) and the amount of available light decreases (the image gets darker) because the high - power objective lens has a smaller aperture and higher magnification.

Answer:

1. 1000 $\mu\mathrm{m}$, 1 mm
2. The field of view decreases and the amount of available light decreases.
