Answer: Fluorescence microscope

Explanation:

The basic function of a fluorescence microscope is to irradiate the specimen with a desired and specific band of wavelengths. A fluorescence microscope uses a mercury or xenon lamp to produce ultraviolet light. The light comes into the microscope and hits a dichroic mirror. The dichroic mirror reflects the ultraviolet light up to the specimen. The ultraviolet light excites fluorescence within molecules in the specimen. The objective lens collects the fluorescent-wavelength light produced. This fluorescent light passes through the dichroic mirror and a barrier filter, making it to the eyepiece to form the image.

What tissue acts as a firm, protective packing around and between organs, bundles of muscle fibers, and nerves?
KengaRu [80]

The Adipose tissue acts as a firm, protective packing around and between organs, bundles of muscle fibers, and nerves. Adipose tissue serves as a key metabolic component in the control of whole body energy homeostasis. While the brown adipose tissue stores lipids for cold-induced adaptive thermogenesis.

Other organs use the white adipose tissue as a vital energy source. In addition to protecting the body from the cold and the heat, cushioning sensitive organs, and secreting hormones and biological chemicals, its main job is to store energy. On the other side, neonates and foetuses tend to have more brown adipose tissues.
