Answer:
endospore-forming
Explanation:
The bacteria shown in the question above have the ability to multiply and grow as noted in the text. This shows the ability of these bacteria to produce spores.
Not all bacteria are capable of producing spores, but those that are produced when they are subjected to adverse environmental conditions, such as the hot water that the bacteria, shown in the question above, submitted. This happened because in order to preserve its species, bacteria enter a process called sporogenesis that is capable of producing and throwing spores in half.
