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.
Answer: Sympathetic Nervous System.
Explanation:
The sympathetic nervous system is part of the autonomic nervous system. The sympathetic nervous system activates what is often termed the fight or flight response. The sympathetic nervous system directs the body's rapid involuntary response to dangerous or stressful situations. A flash flood of hormones boosts the body's alertness and heart rate, sending extra blood to the muscles. Breathing quickens, delivering fresh oxygen to the brain, and an infusion of glucose is shot into the bloodstream for a quick energy boost. The sympathetic nervous system allows animals to make quick internal adjustments and react without having to think about it.
