Question

1. thermus aquaticus is found surviving yellowstone national park’s hot springs. what allows it to live in this environment?

• affinity towards high saline waters
• ability to withstand high temperatures
• ability to produce a lot of methane gas

Explanation:

Thermus aquaticus lives in hot springs, which are high - temperature environments. The first option, affinity towards high saline waters, is incorrect as hot springs in Yellowstone aren't mainly about high salinity for this organism's survival. The third option, ability to produce a lot of methane gas, is also incorrect as this organism's survival in hot springs is related to temperature tolerance, not methane production. So the correct reason is its ability to withstand high temperatures.

Answer:

B. ability to withstand high temperatures
