A mаrine biоlоgist is investigаting why cоrаl reefs are bleaching. They suspect a new chemical in sunscreen, 'Oxybenzone-X,' is the culprit. Oxybenzone-X is thought to disrupt the symbiotic relationship between coral polyps and their internal algae (zooxanthellae) by damaging the algae's photosynthetic membranes. To test this, the biologist sets up two tanks containing coral samples: Tank A is treated with 50 mL of Oxybenzone-X solution, and Tank B is treated with 50 mL of plain seawater. The biologist then measures the percentage of bleached coral in each tank after two weeks. Which of the following is the best scientific mechanistic hypothesis for this study?
