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

I come in different shapes and sizes.
Parts of me are curved, other parts are straight.
You can put me anywhere you like,
but there is only one right place for me.
What am I?

You see me once in June, twice in November, and not at all in May. What am I?

What is full of holes but still holds water?

What am I?

There was a greenhouse.
Inside the greenhouse, there is a white house.
Inside the white house, there is a red house.
Inside the red house, there are lots of babies.

What is It?

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

Spelt forwards I’m what you do every day, spelled backwards I’m something you hate. What am I?

I’m tall when I’m young, and I’m short when I’m old. What am I?

I welcome the day with a show of light, I stealthily came here in the night. I bathe the earthy stuff at dawn, But by noon, alas! I'm gone.
