  15. Mr. Whatsamajig has just returned a sample of water from a planet outside our solar system.  When he opened the container, to his amazement, he found a small bright object.  He carefully set it aside in a container and left it for the evening.  When he returned the next morning he found that it had grown to twice its previous size.  He reasoned, since it grew, that it was a living organism.  In order to see what type of gases it used he decided to set up a BTB experiment.  If you were him tell me how you would set up the experiment.  Tell me your procedure and what you would hope to prove with your experiment.
