Most coral reefs across the world would perish if the surrounding water temperature goes above 31°C. However, the coral reefs in Persian Gulf can withstand temperature up to 35°C. What may be the reason(s) for the same?

  1. Coral reefs of Persian Gulf use different genetic mechanism when compared to corals reefs of other water bodies.
  2. Water in the Persian Gulf is less polluted than other water bodies of the world.

Select the correct code from options given below:

Answer: [A] Only 1

First statement is correct because the algae in Gulf corals belong to a group not known for its thermal tolerance and use different genetic mechanism when compared to corals reefs of other water bodies. Second statement is incorrect because Persian Gulf is small and the water there is generally more polluted due to oil spills in water.
