The supporting tissue that contains non-living extracellular matrix is  

Options

A. cartilage
B. bone
C. both (1) & (2)
D. none

Answer

To solve the question "The supporting tissue that contains non-living extracellular matrix is," we will follow these steps:

### Step 1: Understand the Concept of Supporting Tissues
Supporting tissues are a type of connective tissue that provide structural support to the body. They form the framework and support various organs and structures.

**Hint:** Remember that supporting tissues are part of the connective tissue family.

### Step 2: Identify the Characteristics of Supporting Tissues
Supporting tissues are characterized by their extracellular matrix (ECM), which can be either living or non-living. In this case, we are specifically looking for a supporting tissue with a non-living ECM.

**Hint:** Focus on the definition of extracellular matrix and its role in connective tissues.

### Step 3: Analyze the Options Given
The options provided are:
1. Cartilage
2. Bone
3. Both cartilage and bone
4. None

We need to evaluate which of these options contains a non-living extracellular matrix.

**Hint:** Think about the composition of cartilage and bone.

### Step 4: Examine Each Option
- **Cartilage:** This is a type of connective tissue that has a significant amount of extracellular matrix, but it is primarily composed of living cells and is not considered to have a non-living ECM.

- **Bone:** This is also a type of connective tissue, but it has a substantial non-living extracellular matrix that provides rigidity and strength to the skeleton.

- **Both Cartilage and Bone:** Since cartilage does not contain a non-living ECM, this option is incorrect.

- **None:** This option suggests that neither cartilage nor bone fits the description, which is also incorrect since bone does contain a non-living ECM.

**Hint:** Compare the properties of cartilage and bone to determine which one fits the criteria of having a non-living ECM.

### Step 5: Conclusion
Based on the analysis, the correct answer is **Bone** because it is the supporting tissue that contains a non-living extracellular matrix.

**Final Answer:** Bone (Option 2).
