they are modifications of the epidermis layer, which is avascular, pretty much meaning yes it is dead
Yes, both a cockroach's exoskeleton (skin) and human fingernails are made of a protein called chitin. However, the composition and structure of chitin in a cockroach's exoskeleton are different from the keratin in human fingernails.
dead cells
Fingernails and hair are dead skin cells that have undergone Keratinization. Keratin that has solidified essentially. Keratin is made up of a family of proteins.
Fingernails are made of a special kind of protein called keratin, the same kind of stuff that a cow's hoofs and horns are made of. There are many different kinds of proteins. You need the protein of meat or milk or plant seeds in your diet. But don't chew your fingernails. You can't digest the keratin protein. Keratin is made of dead cells, so is your hair and your first layer of skin! It sounds gross, but I wouldn't change it, though!
Although fingernails are made of a protein called keratin which contains carbon, they are not significant carbon sinks. The amount of carbon stored in fingernails is relatively small compared to other carbon sinks in nature such as forests or oceans.
so that we don't eat the germs which we touch along with our food and get sick. and fingernails are made up of dead skin
It's you dead, hsrden skin!
Yes. As is hair and the outer layer of the skin.
... No. It's dead skin cells.
It protects the skin underneath it. Don't chew your fingernails because they are dead skin. Your skin produces this.
No. they are dead skin cells, or epithelial tissues. Lipids are fats
Scaly skin, their scales are made out of what are fingernails are made out of. i hope this helps :)

no soap isn't made out of dead skin but if you want to know your hair is made out of dead skin cells
