Helping others is my role, I make your actions reach their goal. What am I?

I fly through air, not by wings, But by a throw or mechanical things. What am I?

I was once accepted, now I’m not, I’ve been pushed out of the chosen spot. What am I?

Sadness hit me, I felt down, Like emotions had just thrown me to the ground. What am I?

I’m a patch of Earth or land so wide, People fight to claim my side. What am I?

I’m Earth inside a glassy dome, For plants or creatures to call home. What am I?

I’m a level place above the ground, Where views are nice and peace is found. What am I?

I do the job without a hand, No help needed, I understand. What am I?

I work alone, I lead, I steer, No one tells me to shift a gear. What am I?

I help machines take over the task, Saving time—no need to ask. What am I?

Two living things help one another, Like best friends or nature’s brother. What am I?

I’m a danger to life, so beware! You’ll see my sign with skulls that stare. What am I?

A tiny cut, a piece removed, To study how your cells have moved. What am I?
