Not quite sure what the point of the first one is,
The second and third seem quite detailed, particularly like how a lone rabbit is dead, and it does touch an important point that you've made me consider just how difficult it is to define "life"

he last one listing developmental stages makes me consider, IMO that the UK cut off at 24 weeks is the correct point at which to distinguish from something that you can terminate, and a viable life form. Other people may look at the list and judge differently, but if they'd like to demonstrate lving without working lungs...(for a person, obviously many things in nature don't have lungs....)
