Answer:
the ability to live in a highly acidic environment
the ability to withstand very hot temperatures
Explanation:
The main feature of Yellowstone National Park is the presence of extremely hot and acidic water. Therefore, for a bacteria to live in this environment it has to adapt quickly, exhibiting the ability to be resistant to acids and high temperatures. This allows a great resistance in the bacteria and also stimulates that they present greater solubility, higher diffusion rate and lower reaction rates.
