-Stereomicroscope
A)Observing insects
B)Three-dimensional images
C)Cytoplasmic streaming
D)Fluorescent dye
E)Ultrathin sectioned specimens

Accepted Answer

Stereomicroscopes are commonly used for observing insects due to their ability to provide a magnified, three-dimensional view of the specimen.

Answer: B
 Stereomicroscopes are capable of producing three-dimensional images, making them useful for examining specimens with depth or texture.

Answer: C
 Cytoplasmic streaming can be observed using a microscope that has a high-resolution video camera and allows for real-time observations.

Answer: D
 Some stereomicroscopes may be equipped with fluorescent filters, allowing for the visualization of fluorescent dyes in specimens.

Answer: E
 Ultrathin sectioned specimens require a transmission electron microscope due to their delicate and thin nature. Stereomicroscopes are not suited for this type of imaging.
