Ties One Another
What ties one to another and is closest to the heart?

I know, this is nearly a duplicate with What Holds Two People Together.

At night they come without being fetched. By day they are lost without being stolen. What are they?
The stars.
Reaching Stiffly For The Sky
Reaching stiffly for the sky,
I bare my fingers when it’s cold
In warmth I wear an emerald glove
And in between I dress in gold
A deciduous tree.
I Sleep By Day
I sleep by day, I fly by night. I have no feathers to aid my flight. What am I?
A bat.
Toss Me Out the Window
Toss me out of the window,
You’ll find a grieving wife,
Pull me back but through the door, and
Watch someone give life!
What am I?
The letter “n”. (widow, donor).
Favorite Pet is a Fish
I died and came back to life. My blood is not easily able to go through my body. My favorite pet is a fish. Who am I?
A shark. Sharks experience tonic immobility, also known as apparent death, where they appear to have died. Blood does not easily flow through their bodies, forcing sharks to swim continuously to circulate their blood. Lastly, sharks have pet fish called Remora (sometimes called suckerfish). They feed on parasites on the sharks and leftovers, and they use the shark as transport and protection.
A big thanks to Saravana for answering this.
I Always Send You In The Right Direction
I always send you in the right direction,
I’m arrayed in black and white,
Ignore me and lose my protection,
No more than two words are in sight.
What am I?

A one way street sign. It tells you the correct way to go, is black and white (in the United States), going the wrong way can get you a citation and the sign only has two words on it.
