Question

Immersion oil can only be used with the 100X objective lens. The oil must be properly removed before using the 4X, 10X, or 40X objectives lenses. This statement belongs to which subject?

a) Biology
b) Physics
c) Chemistry
d) Medicine

Answer 1

The statement belongs to the subject of Biology.

Step-by-step explanation:

The statement belongs to the subject of Biology. Oil immersion is a technique used in microscopy to improve resolution. When using the oil immersion objective, you must use immersion oil to fill the space between the specimen and the lens, as the oil has a refractive index similar to that of glass and increases the resolution of the image. However, you should not use oil with the other objective lenses as it can damage them and the microscope.
