Answer

To determine which animal is not an example of a bisexual (hermaphrodite) organism, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Bisexual (Hermaphrodite) Animals**:
- Bisexual or hermaphrodite animals possess both male and female reproductive organs. This allows them to produce both male and female gametes.

2. **Identify the Options Provided**:
- The question likely provides a list of animals. For this solution, we will consider the animals mentioned in the transcript: Earthworm, Sponge, Tapeworm, Leech, and Cockroach.

3. **Evaluate Each Animal**:
- **Earthworm**: Earthworms are hermaphrodites, meaning they have both male and female reproductive organs.
- **Sponge**: Sponges can be either unisex or bisexual. They can have both reproductive organs in some species.
- **Tapeworm**: Tapeworms are also hermaphrodites, having both male and female reproductive structures.
- **Leech**: Leeches are typically hermaphroditic as well, possessing both types of reproductive organs.
- **Cockroach**: Cockroaches are not hermaphrodites; they have distinct male and female individuals, making them unisex.

4. **Determine the Correct Answer**:
- Based on the evaluations, the cockroach is the only animal listed that is not a hermaphrodite. Therefore, the answer to the question is the cockroach.

### Final Answer:
The animal that is not an example of a bisexual (hermaphrodite) organism is the **Cockroach**.
