The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Hydra's Regeneration**: Hydra is a member of the phylum Cnidaria, known for its remarkable ability to regenerate. This means that if it is broken into pieces, it has the potential to reform into complete organisms. 2. **Role of Interstitial Cells**: The key to Hydra's regeneration lies in the presence of interstitial cells. These cells are reserve cells that can differentiate into various types of cells necessary for forming different tissues in the organism. 3. **Location of Interstitial Cells**: Interstitial cells are found in both the epidermis (outer layer) and gastrodermis (inner layer) of Hydra. They are crucial for regeneration as they provide the necessary cells to rebuild the organism. 4. **Fragmentation and Regeneration**: When Hydra is broken into pieces, those fragments that contain interstitial cells will be capable of regenerating into complete Hydras. The fragments that lack these cells will not be able to regenerate. 5. **Conclusion**: Therefore, the correct answer to the question is that some fragments of Hydra will form complete Hydras, provided they contain the interstitial cells necessary for regeneration.
