Organisms that survive in varied temperatures adapt to chang

Organisms that survive in varied temperatures adapt to changes by using supercoiling. hyperosmotic molecules. countercurrent circulation. isozymes. Coral bleaching occurs when coral exoskeletons begin to break down. is due to a lack of dissolved nutrients from the surrounding water. is a temporary process that is usually reversed within days. occurs when algae are expelled from coral. The primary cause of coral bleaching is decreased water temperature. increased water temperature. decreased salt concentrations. increased water pH. decreased water pH

Solution

17. Option C. Counter current circulation.

Heat exchange or conservation can be achieved by counter current circulation.

18. Option D. Occurs When algae are expelled from coral

19. Option B. Increased water temperature

When the water temperature increases, algae are expelled from the corals making them to appear white or bleached
