Questions: Question 10 1.25 pts Which type of microscopy do we use in the lab at TWU (most common type of microscope used in all biology classes)? Darkfield microscopy Brightfield micrscopy Electron microscopy

The answer is the second one: Brightfield microscopy.

Explanation for each option:

1. Darkfield microscopy: This type of microscopy is used to enhance the contrast in unstained samples. It is not the most common type used in general biology classes, as it is more specialized.

2. Brightfield microscopy: This is the most common type of microscopy used in biology labs, including at TWU. It involves illuminating the sample with white light and is suitable for observing stained or naturally pigmented specimens.

3. Electron microscopy: This type of microscopy uses a beam of electrons to create an image and is used for very high-resolution imaging. It is not typically used in general biology classes due to its complexity and cost.

In summary, brightfield microscopy is the most commonly used type in biology classes due to its simplicity and effectiveness for a wide range of samples.
