Restorative regeneration in common in

Options

A. Vertebrates
B. Mostly invertebrates
C. In some vertebrate groups
D. In some invertebrate groups

Answer

**Step-by-Step Solution:**

1. **Understanding Restorative Regeneration**: Restorative regeneration refers to the process by which an organism can regrow or replace parts of its body that have been lost due to injury or other reasons. This is a biological phenomenon observed in various organisms.

2. **Identifying the Groups**: Regeneration can occur in both vertebrates (animals with a backbone) and invertebrates (animals without a backbone). However, the extent and efficiency of restorative regeneration can vary significantly between different groups.

3. **Vertebrates and Invertebrates**: While some vertebrates exhibit regenerative capabilities (like certain species of salamanders), it is more commonly observed in invertebrates such as starfish, planarians, and some species of worms.

4. **Conclusion**: Based on the understanding that restorative regeneration is more prevalent in certain invertebrate groups than in vertebrates, we can conclude that the correct answer to the question is that restorative regeneration is common in some invertebrate groups.

5. **Final Answer**: Restorative regeneration is common in some invertebrate groups.
