life
/laɪf/
In a biological sense, this term defines the fundamental state of existence characterized by metabolism, growth, and reproduction. It serves as the primary boundary between the organic world and the inert, chemical composition of minerals and gases. When used in an astrophysical or xenobiological context, the word shifts from a description of known organisms to a search for any detectable biological signature, regardless of how alien the chemistry might be compared to Earth.
Uncountable as a biological concept; countable when referring to specific organisms.

I think so, but I'm just winging it with the microscope.
