The embryo technically develops in a cavity of the “body” of the mother. It is neither limb nor organ (vital or not) of the ‘host organism’ (mother). It is a distinct organism. The open Q is at what point it is a ‘human being’ with associated rights. (Just for FYI, in Islam this transition is held to occur after the development of eyes after which abortion is not acceptable. [I believe this window of ‘choice’ for parents is the first trimester.])

Eviction is not something a landlord may decide on their own. Typically you have to take the tenant to court. Sometimes in fact they do end up staying rent free for months.
