1. She could see if it responds to external stimuli.
Ex.) Poking it with her finger to see if it responds
2. She could see if it eats any food
Ex.) attempting to feed it lettuce, meat, or to see if it photosynthesises etc.
3. She can see if it moves in any manner.
Ex.) walking, swimming, so on.
Other things she could do include testing it to see if it grows whether as it grows older and matures or grows roots or longer hair. Another thing she could do is find if it creates any waste products, scat, carbon dioxide. Another thing she could also check is it is able to reproduce. Lastly, making sure it has a cellular structure and breathes.
Hope this helps! :)
