2. Your friend has just returned from a deep sea mission and claims to have found a new single-celled life form.

In order to verify or dispute your friend’s claim, you realize that you must first make a list of characteristics common to all prokaryotes and eukaryotes, so that you can check whether this new life form is different in some fundamental characteristic from all other types of life on Earth.
