Assume the diameter of the field of vision in your microscope is 2mm under low power. if one bacillus cell is 2um, how many bacillus cells could fit end across the field? how many 10um yeast cells could fit across the field?
2) name two ways in which you can enhance the resolving power.
3) what are the advantages of the low-power objective over the oil immersion objective for viewing fungi or algae?
4) what would occur if water were accidentally used in place of immersion oil?
5) which controls on the microscope affect the amount of light reaching the ocular lens?
6) which objective focuses closest to the slide when it is in focus?
7) why is it desirable that microscope objectives be parfocal?
8) in bacteria, fungi, protozoa and algae, which one is the largest organism, which one is the smallest?
9) how does increased magnification affect the field of vision.

1. If one bacillus is 2um, then 1000 bacillus could fit end across the field.

Also

200 yeast cell fit across the field.

2. Ways in which you can enhance the resolving power are

a. Adjustment of numerical aperture

b. Immersion oil

3. It helps you to get a better view of fungi or algae because they are larger organism

4. If water accidentally used in place of immersion oil the image would not be clear.

5. The diaphragm and the light intensity adjustment.

6. The immersion oil objective (100x)

7. Because you do not have to refocus the microscope every time you switch the lenses.

8. Protozoa is the largest organism while virus is the smallest.

9. Because you are essentially looking closer and closer at the object.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
