Which is not connected with theory of ageing

Options

A. Wear and tear
B. Neuroharmonal changes
C. Epimorphosis
D. Metabolic rate

Answer

To determine which option is not connected with the theory of aging, we will analyze each option provided in the question: wear and tear, neurohormonal changes, epimorphosis, and metabolic rate.

### Step-by-Step Solution:

1. **Understanding Aging**: Aging is a complex process characterized by a gradual decline in physiological functions and physical activity. It involves various biological changes that affect the body's ability to repair and regenerate.

2. **Analyzing Wear and Tear**:
- Wear and tear refers to the cumulative damage to tissues and organs over time.
- As individuals age, their bodies experience increased wear and tear, leading to a decline in physical capabilities.
- **Conclusion**: Wear and tear is connected with the theory of aging.

3. **Analyzing Neurohormonal Changes**:
- Neurohormonal changes involve alterations in hormone levels and nervous system function as one ages.
- These changes can affect mood, behavior, and overall physiological responses.
- **Conclusion**: Neurohormonal changes are connected with the theory of aging.

4. **Analyzing Epimorphosis**:
- Epimorphosis is the process of regeneration, where organisms can restore lost body parts or heal wounds.
- In aging, the ability to regenerate and heal diminishes significantly.
- **Conclusion**: Epimorphosis is not connected with the theory of aging, as the regenerative ability declines with age.

5. **Analyzing Metabolic Rate**:
- Metabolic rate refers to the rate at which the body converts food into energy.
- With aging, metabolic rate generally decreases, leading to various health issues.
- **Conclusion**: Metabolic rate is connected with the theory of aging.

6. **Final Decision**: Based on the analysis, the option that is not connected with the theory of aging is **Epimorphosis**.

### Answer:
**C. Epimorphosis**
