Changes that allow the conversion of larve into adult, is called :

Options

A. Metagenesis
B. Alternation
C. Metamorphosis
D. Metastasis

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks for the term that describes the changes allowing the conversion of a larva into an adult organism.

2. **Identifying the Process:**
The process that describes the transformation from larva to adult is known as "metamorphosis." This term specifically refers to the series of physical changes that occur during the life cycle of certain organisms.

3. **Life Cycle Stages:**
- The life cycle begins with an egg, which hatches into a larva.
- The larva undergoes changes and eventually transforms into a pupa.
- Finally, from the pupa, the adult form emerges.

4. **Conclusion:**
Therefore, the correct answer to the question is "metamorphosis."

5. **Elimination of Other Options:**
- **Metagenesis:** Refers to the alternation of generations, where both sexual and asexual phases occur (e.g., in cnidarians).
- **Metastasis:** Refers to the spread of cancer cells from one part of the body to another, which is unrelated to larval development.
- **Alteration:** This term is often associated with metagenesis and does not specifically refer to the transformation from larva to adult.

6. **Final Answer:**
The changes that allow the conversion of larva into adult are called "metamorphosis."
