You grow the bacteria found in a dried soup from a 4,000-year-old cooking pot found in an Egyptian tomb and obtain a distinctive species of prokaryote. You immerse a test tube of these bacteria in boiling water for several hours, but find the the bacteria can divide and grow. This species is probably

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.

and after water is usually warmed by the sun the water temperature raises and then evaporates .
