Taste of food evokes salivation by a reflex while smell of food causes salivation by a ____________reflex

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question states that the taste of food evokes salivation through a reflex, while the smell of food causes salivation by a different type of reflex. We need to identify the type of reflex associated with the smell of food.

2. **Identifying Reflex Types**: Reflexes can be categorized into two main types:
- **Unconditioned Reflex**: This is a natural, automatic response to a stimulus (e.g., salivation when food is tasted).
- **Conditioned Reflex**: This is a learned response that occurs when a neutral stimulus is associated with an unconditioned stimulus (e.g., salivation in response to the smell of food, which is learned over time).

3. **Analyzing Salivation Triggers**:
- When food is tasted, the body naturally salivates; this is an unconditioned reflex.
- When food is smelled, the body can also salivate, but this response is learned through association with the experience of eating. This is a conditioned reflex.

4. **Conclusion**: Therefore, the smell of food causes salivation by a **conditioned reflex**.

**Final Answer**: The smell of food causes salivation by a **conditioned reflex**.
