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.

the plant cell when placed under hypertonic medium,it loses a great amount of water and its cell membrane detaches from the cell wall.in this situation the cell is called plasmolysed cell.when the plasmolysed cell is placed in hypertonic medium it absorbs water and becomes a turgid cell.this phenomenon is called deplasmolysis.</span>
I’ll go with False? Mainly because I’m thinking that some genes may change in the body overtime. Like a mutation of the DNA that might change the cell(s).
the answer is A because restriction enzymes function in cutting strand of DNA at specufic sites
