Text Solution

Verified by Experts

The correct answer is:

Microbes living at extremely high temperatures (thermophiles) survive because of several adaptations:

• Branched lipid chains make cell membranes more stable.

• Less free water helps prevent damage at high temperatures.

• Heat-tolerant enzymes remain functional even above 100°C.
