The mature proglottids having fertilized eggs in the uterus of tapeworm are regularly dtached. This process is known as

Options

A. Apolysis
B. Proliferation
C. Strobilation
D. Topolysis

Answer

To answer the question regarding the process by which mature proglottids containing fertilized eggs are regularly detached from a tapeworm, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organism**: Recognize that the organism in question is a tapeworm, which belongs to the phylum Platyhelminthes and the class Cestoda.

2. **Understand Proglottids**: Tapeworms have a segmented body structure made up of segments called proglottids. These proglottids can be mature and contain fertilized eggs.

3. **Process of Detachment**: The mature proglottids that contain fertilized eggs are regularly detached from the main body of the tapeworm.

4. **Name the Process**: The specific term for the detachment of these mature proglottids is known as "apolysis."

5. **Purpose of Apolysis**: This process serves two main purposes:
- It helps in the transfer of developing embryos to the exterior environment where they can be ingested by a secondary host.
- It limits the size of the tapeworm's body, preventing it from growing excessively long due to continuous proliferation in the neck region.

6. **Conclusion**: Therefore, the correct answer to the question is that the process by which mature proglottids are regularly detached is called **apolysis**.
