Let's go check it out. Wait! What if its alive? There are eight characteristics of life. First, we checked if it was made of cells. It must be multi cellular, its huge! I'll check with my x ray goggles. I see cells, tissues, organs, and systems, it is multi cellular! Then we found out whether or not it could reproduce. Look! It's baby is coming! Aw! Look how small it i- *screech* Oh my gosh! Cut the camera! Cut the camera! *beep* Next we saw if it made or ate food to get energy. Look, it is a heterotroph, Next we say if it made or ate food to get energy Look! Its a heterotroph, obtaining energy from other organisms, like carrots. Then, we found out if it could maintain its body conditions through homeostasis. One way an animal maintains homeostasis is to release waste. Look, it pooped! The next characteristic was a bit difficult to see. DNA! DNA, hmm, I think I might need my x ray goggles again. You will need to magnify them all the way to see the teeny tiny chromatin wrapped up in the nucleus of the cells. I see it! Next, we checked if it grew and developed. It looks a lot bigger. It must have grown from eating all those carrots. Then we checked for adaptations to its environments. Its fur seems to be coming off. It must be shedding because it is getting a lot warmer outside. There is only one more characteristic to check off... Its response to stimuli! Rachel, look. Who is that? Hey look at this cute little bunny rabbit! It has responded to the stimuli of this crazy woman's touch! It must be ALIVE!
