A scientist cultures the dried soup from a 4,000-year-old cooking pot found in an Egyptian tomb and obtains a distinctive species of prokaryote. She immerses a test tube of these bacteria in boiling water for several hours, but the colony grows back. This species is probably.

Endospore-forming.

Explanation:

Prokaryotes may be defined as the organism that lacks the nucleus and membrane bound cell organelles. Prokaryotes are smaller in size and simple as compared with eukaryotes.

The endospore formation occur in some species of prokaryotes. Endospores are hard, tough covering of the spores to protect them from the harsh environmental conditions. The colony can grow back this means the species has the ability form endospore.

Thus, the answer is endospore forming.  

just here for the other one bc they put up with u

the answer is a) a shiprock was formed by igneous process
