QUESTION:
While walking in the woods, you discover a large rock covered with a gelatinous, sticky substance. What test could you perform to determine whether the substance is inanimate, alive, or the product of a living organism?
ANSWER:Step 1 of 2
A thing is considered living if it can fulfill all the characteristics of being alive. A living thing is made up of cells organized in a particular fashion. Living things exchange material from the environment such as light, glucose, and air, which they metabolize for their energy needs and return as waste to the environment. The living thing grows, develops, and reproduces. A living thing can respond to any change or stimuli in its environment. Anything that fulfills only a few characteristics above cannot be considered alive. All the characteristics mentioned above must hold for that living thing.
