Answer

To solve the matching question, we will go through each item in Column I and find the correct match in Column II step by step.

### Step-by-Step Solution:

1. **Biomacromolecules**:
- Definition: Biomacromolecules are large biological polymers such as proteins, nucleic acids, and carbohydrates.
- Function: They are broken down into simpler substances during digestion.
- **Match**: (iv) Converted into simple substances.

2. **Human Digestive System**:
- Definition: The human digestive system consists of the gastrointestinal tract and associated glands (like salivary glands, pancreas, liver).
- Function: It is responsible for the digestion and absorption of food.
- **Match**: (i) Alimentary canal and associated gland.

3. **Stomach**:
- Definition: The stomach is a muscular organ located in the upper abdomen.
- Function: It has a J-shaped structure and acts as a storage and mixing chamber for food.
- **Match**: (v) J-shaped bag like structure.

4. **Thecodont**:
- Definition: Thecodont refers to a type of dentition where teeth are embedded in sockets in the jawbone.
- Examples: Found in mammals, crocodilians, and dinosaurs.
- **Match**: (ii) Embedded in jawbones.

5. **Serosa**:
- Definition: Serosa is a smooth tissue membrane that lines the outer wall of visceral organs.
- Function: It secretes serous fluid to lubricate the organs.
- **Match**: (iii) Outer wall of visceral organs.

### Final Matches:
- Biomacromolecules → (iv) Converted into simple substances
- Human Digestive System → (i) Alimentary canal and associated gland
- Stomach → (v) J-shaped bag like structure
- Thecodont → (ii) Embedded in jawbones
- Serosa → (iii) Outer wall of visceral organs

### Summary of Matches:
- Biomacromolecules → (iv)
- Human Digestive System → (i)
- Stomach → (v)
- Thecodont → (ii)
- Serosa → (iii)
