Answer:
Spontaneous generation / abiogenesis
Explanation:
Long ago, philosopher still debating where did living organism come from. Aristotle came up and hypothesized that living being can come from inanimate matter (without any genetic transfers from the parents of that particular organism) . This theory called spontaneous generation.
Spontaneous generation had later on proven to be false and living being is not spontaneously created, but come from reproduction of the same species which passed on their genes to the next generation.

Answer:
<h2>
lack antibiotic resistant genes</h2>
Explanation:
Most of the bacterium contains plasmid. As given, if bacterium regenerates from an endospore that did not possess any of the plasmids so the generated bacterium also lack antibiotic resistant genes.
Plasmid are circular form of extra chromosomal DNA that contain genes for antibiotic resistant and genes for conjugation , and also for many other roles.
Plasmid replicate independently of the chromosomal DNA, and can be many in number. If the bacterium lacks plasmid so these bacterium also lack antibiotic resistant genes.
