I shave every day, but my beard stays the same. What am I?

Two in a corner, one in a room, zero in a house, but one in a shelter. What am I?

What is in seasons, seconds, centuries and minutes but not in decades, years or days?

Until it is measured, not known. Yet how you miss it when it has gone. What is it?

A father's child, a mother's child, yet no one's son.

Who am I?

When it is alive we sing, when it is dead we clap our hands. What is it?

I am a five-letter word and people eat me. If you remove the first letter I become an energy form. If you remove the first two letters, I am needed to live. Scramble the last three letters and I am a drink. What word am I?

When you say goodbye, I am what you need to tie.
I come as a couple and go wherever you run.
Who am I?

Take one out and scratch my head, I am now black but once was red. What am I?

It's pretty hard to give up.
If you remove a part of it, you will be left with a bit.
Even if you remove another part, the bit still remains.
Remove one more and it still remains.

What is it?
