Each cell becomes a thin plate; these plates pile into layers to form the nail. As with hair, nails form by keratinization. When the nail cells accumulate, the nail pushes forward. The skin below the nail is the matrix.
Hair is made of a tough protein called keratin. A hair follicle anchors each hair into the skin. In the hair bulb, living cells divide and grow to build the hair shaft. Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life
Nails start in the nail root, hidden under the cuticle. When cells at the root of the nail grow, the new nail cells push out the old nail cells. These old cells flatten and harden, thanks to keratin, a protein made by these cells. The newly formed nail then slides along the nail bed, the flat surface under your nails.

If the have a vitamin deficent or anemia as well as a doctor remoceded them increase in their viamin intake.
Explanation:
Resolution is the ability that a microscope has to distinguish fine details. Without making any other adjustments the RESOLUTION can be increased by focusing properly in a brightfield microscope.
A brightfield microscope (also called compound light microscope) is a light microscope that produces dark images against a bright background.
The brightfield microscope is widely used in cellular biology and microbiological laboratories.
The resolution of the brightfield microscope is limited to 0.2 micrometers (µm).
This maximum value can be reached by changing the objective lens.
