The correct Answer is:
To answer the question, we need to fill in the blanks regarding the neural organization in different organisms. Let's break it down step by step: ### Step-by-Step Solution: 1. **Understanding Neural Organization**: - Neural organization refers to how neurons (nerve cells) are arranged in an organism. - Some organisms have a simple network of neurons, while others have more complex structures. 2. **Identifying the First Blank**: - The question states that neural organization is composed of a network of neurons. - This description fits **Hydra**, a simple organism that has a decentralized nerve net. - In Hydra, neurons are interconnected, forming a network that allows for basic responses to stimuli. 3. **Identifying the Second Blank**: - The second part of the question asks where neural organization is present in the form of neural tissue. - Insects, which belong to the phylum Arthropoda, have a more complex nervous system. - Insects have a centralized nervous system with a brain and a ventral nerve cord, which is organized into neural tissue. 4. **Final Answer**: - Therefore, the complete answer to the question is: - Neural organization is composed of a network of neurons in **Hydra**, whereas it is present in the form of neural tissue in **Insects**. ### Answer: Neural organization is composed of a network of neurons in **Hydra**, whereas it is present in the form of neural tissue in **Insects**. ---
