Why do we have nail?
The short answer is we have evolved to have nails because they help us pick things up (like food), pick things off (like bugs), and hold tightly onto things.

Is a sperm cell a baby?
If an ovum has been released, and the couple have sex, a sperm can unite with it, fertilise it and make the first cell of a new baby. Once one sperm has fertilised the ovum, no other sperm can get in. For the sperm it’s like a race and there is only one winner.
Does your hair grow after you die?
Hair and fingernails may appear longer after death, but not because they are still growing. … After death, dehydration causes the skin and other soft tissues to shrink.

The hyponychium (informally known as the “quick”) is the epithelium located beneath the nail plate at the junction between the free edge and the skin of the fingertip. It forms a seal that protects the nail bed. The onychodermal band is the seal between the nail plate and the hyponychium.
