The correct Answer is:
To determine which organism has a closed circulatory system, we will analyze each of the given options step by step. ### Step-by-Step Solution: 1. **Understanding Closed Circulatory System**: - A closed circulatory system is one where the blood circulates within closed vessels (arteries, veins, and capillaries). This is in contrast to an open circulatory system, where blood is not confined to vessels and bathes the organs directly. 2. **Analyzing the Options**: - **Option A: Locusta** (Grasshopper) - Locusta belongs to the phylum Arthropoda. Members of this phylum typically have an open circulatory system. Therefore, Locusta does not have a closed circulatory system. - **Option B: Saccuglossus** - Saccuglossus is a member of the phylum Hemichordata. Similar to Arthropoda, Hemichordates also have an open circulatory system. Thus, Saccuglossus does not have a closed circulatory system. - **Option C: Neeris** - Neeris is a member of the phylum Annelida. Annelids, such as earthworms, possess a closed circulatory system, where blood is contained within vessels. Therefore, Neeris does have a closed circulatory system. - **Option D: Eschirus** - Eschirus belongs to the phylum Nematoda. Nematodes have a very simple body plan and do not possess a circulatory system at all. Hence, Eschirus does not have a closed circulatory system. 3. **Conclusion**: - After analyzing all the options, we find that only Neeris has a closed circulatory system. Therefore, the correct answer is **C: Neeris**.
