It is TRUE that coral reefs form when a<span> structure of calcite skeletons built up by coral animals in warm, shallow ocean water. </span>To form their skeletons, coral animals absorb the element calcium from the ocean water. The calcium is then combined with carbon and oxygen to form calcite (calcite is a mineral). When coral animals die, their skeletons remain. More corals build on top of them, gradually forming a coral reef.
Answer:
The answer is A) Homologous structures
Explanation:
Homologous Structures:
- Homologous structures are anatomical features in an organism that are structurally and functionally diverse but they originate from a single common ancestor.
- Homologous structures possess a similar basic internal structure but can have entirely different morphology and function.
- For example, the wings of a bat and a human's arm have the same internal structure but they have different functions.
- Vestigial structures are evolutionary remnants that no longer serve a purpose in modern forms or descendants of the original organism.
- Inherited and developmental are out of context in terms of evolutionary relationships.
