Explain how endospore-forming bacteria could cause a scientist to believe in spontaneous generation. - ANSWER A bacterial endospore is an organism that is able to survive in extreme conditions due to their tough structure. Endospore-forming bacteria could cause scientists to believe in spontaneous generation because, they can survive in extreme conditions that would normally kill bacteria. In spontaneous generation, it is said that living things appear from vital forces existing in nonliving or decomposing matter, but there could be bacterial endospore living in that situation without the scientists knowing.
