The correct Answer is:
To answer the question about the features of Ascaris, we will analyze each option provided. 1. **Complete Digestive System**: Ascaris has a complete digestive system, which means it has a distinct mouth and anus. This is a characteristic feature of many nematodes, including Ascaris. Therefore, this feature is true for Ascaris. 2. **Indirect Development**: Ascaris undergoes indirect development, which means that the organism develops from a zygote into an adult without going through a larval stage. This is also a true feature of Ascaris. 3. **External Fertilization**: Ascaris does not have external fertilization. Instead, it exhibits internal fertilization, where the fertilization of the eggs occurs inside the female's body. This statement is false regarding Ascaris. 4. **Parasitic Life**: Ascaris is indeed a parasitic organism, living in the intestines of its host (usually humans). This feature is also true. Based on the analysis, the option that is not a feature of Ascaris is **external fertilization**. ### Final Answer: Ascaris has all of the following features, except **external fertilization**.
