A fingernail weighs about as much as a postage stamp. A postage stamp weighs about one gram. It would take about 28 fingernails to equal one ounce or about 450 for a pound.
Nails are tools ,have a look at our animal counterparts.
The nail bed is there for the nail to be joined to the finger ,and that is the nailbeds task.
Its part of the whole nail.
The nail is simply a tool.
In our case its not for hunting like some of out animal counterparts.
We use it for aiding in healing ,scratching ,grooming and so forth.
The nail was not designed for the nailbed ,to protect the nailbed ,but the nailbed rather in aid for nail growth.
Lose the whole nail and nailbed and skin wil cover the loss.
Without fingernails, we couldn't grip things well. Nails helps us hold something much better.
Toe nails ,have the same functions as our finger nails.
Or had the same function in the past.
Our nails would be shaped differently if we had fur.
== == Cilia are microtubule-based hair-like organelles that extend from the surface of almost all cell types of the human body. Cilia are hair-like projections that move in a sweeping motion to move things along. For instance there are cilia in the female's fallopian tubes to sweep the egg towards the uterus, and there are cilia in the respiratory tract to sweep inhaled particles back up towards the mouth to get them out of the lungs. Hair-like extensions that protrude from the surface of some unicellular organisms and from some cells in multicellular organisms. A cillia is a small hairlike structures that move small particles of dirt out of the respirtory system(small hair looking things that move clumps of dirt out of the respirtoy system) :). LOL. Hope this answer helps with science. I know it did for me !!!

Hope this answer helps with science. I know it did for me !!! cillia are a kind of flagellate that help a paramecium or any protist that has them move around All of the airways have small hairs called Cillia Cilia is Hairlike projections in the nose that increase the surface area of a cell, increasing it's ability to trap dust, pollen, and other foreign matter to prevent it from entering the nasal cavity.
tiny hairs that trap pathogens. Cilia are very small, hair like organelles. They line the surface of different cells and beat in a rhythmic way that produces waves. These waves move ciliate protozoans and liquids down the internal epithial tissue in many animals.
