Corals are small animals that live in colonies in the ocean They build a hard skeleton like structure using minerals they absorb from the water Each animal in the colony lives in a small hole in the structure Acidic ocean conditions make it difficult for corals to produce the skeleton In a species called smooth cauliflower corals scientists have discovered a genetic variation that allows them to build skeletons with larger holes Corals with this variation need to build less skeleton as they grow Which phenotype is most likely to become more common as smooth cauliflower corals adapt to increasing acidity in the ocean OA No skeletons B Larger skeleton holes OC No skeleton holes D Smaller skeleton holes
