Extreme Hypothermophiles: Archaea or Bacteria?

Are extreme hypothermophiles usually archaea or bacteria?

1) Archaea
2) Bacteria
3) Both archaea and bacteria
4) Neither archaea nor bacteria
Final answer:

Answer:

Extreme hypothermophiles are usually found in the domain Archaea. Therefore, the correct option is 1.

Explanation: Extreme hypothermophiles, organisms thriving in extremely high-temperature environments, are typically associated with archaea rather than bacteria. Archaea is the correct choice. Archaea constitute one of the three domains of life, alongside bacteria and eukaryotes, and many extremophiles, including hyperthermophiles, acidophiles, and halophiles, are found within the archaeal domain. Thermophiles, specifically hyperthermophiles, are adapted to extremely high temperatures, often exceeding 80 degrees Celsius (176 degrees Fahrenheit) or more. These organisms are crucial in ecological niches such as deep-sea hydrothermal vents and hot springs. While certain bacteria can also be thermophiles, extreme hypothermophiles are more commonly associated with archaea.

Therefore, the correct option is 1.
