Fingernails are primarily composed of a protein called keratin, which is also found in hair and skin. The structure of nails includes layers of keratinized cells, making them strong and resilient. Additionally, nails may contain small amounts of minerals, such as calcium and zinc, which contribute to their health and growth. nail polish and artificial nails can be made from various materials, including acrylics, gels, and resins.
Keratin
Alpha-Keratin
acrylic Acrylic nails are generally safe, but can increase the risk of infection under the nail.
It is the same material but muck thicker. Same with your hair. Fingernails, human hair, and a horses hoof are all the same material. So yes.
Yes.
Fingernails are made of a protein called keratin and are considered non-living material, as they do not contain cells or have the ability to grow or repair themselves.
The emery board is used to file the fingernails.
Fingernails are biotic, meaning they are derived from living organisms (the cells in the nail matrix), but once they are fully formed, they are considered to be made of abiotic material (keratin).
Rhinoceros horns are made out of solid keratin. Keratin is the same material that fingernails and hair are made of. Also like fingernails, the horn can grow back if it is cut.
Walruses dont have trunks. There tusk is made from dendrite, the same material as your fingernails
I believe that exoskeletons are made of the same material as our own fingernails and hair, just compacted together.
Rhinos do not have tusks, but their horns are made from compacted hair and keratin (the same material as fingernails).
