Answer

To answer the question "Two bones are attached to each other by," we will analyze the options provided and determine the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding the Question**: The question is asking about the type of connective tissue that connects two bones together.

2. **Analyzing the Options**:
- **Tendons**: Tendons are connective tissues that attach muscles to bones. Since the question is about connecting bones to each other, tendons are not the correct answer.
- **Adipose Tissue**: Adipose tissue is a type of connective tissue that stores fat. It does not play a role in connecting bones, so this option is also incorrect.
- **Ligaments**: Ligaments are fibrous connective tissues that connect bones to other bones at joints. This makes ligaments the correct answer for the question.
- **Dense Irregular Tissue**: This type of tissue provides strength and support in multiple directions but does not specifically connect bones to each other. Therefore, this option is not correct.

3. **Conclusion**: Based on the analysis of the options, the correct answer is **ligaments**.

### Final Answer:
Two bones are attached to each other by **ligaments**.
