Mark the correct pair.

Options

A. Migration - Polar bear
B. Diapause - Zooplanktons
C. Diapause - Desert lizards
D. Suspend- Locust

Answer

To solve the question, we need to analyze each option and determine which pair is correct based on the definitions and characteristics of the terms involved.

### Step-by-Step Solution:

1. **Understanding Migration:**
- Migration refers to the long-distance movement of animals, typically in search of food, shelter, or breeding grounds.
- **Polar Bear:** Polar bears are primarily found in the Arctic regions and do not exhibit long-distance migration patterns like some other species. They may roam over large areas, but this is not classified as migration in the traditional sense.
- **Conclusion:** The pair "Migration - Polar Bear" is incorrect.

2. **Understanding Diapause:**
- Diapause is a period of suspended development or dormancy in response to environmental conditions, allowing organisms to survive unfavorable conditions.
- **Zooplankton:** Many zooplankton species enter a state of diapause to survive harsh environmental conditions, such as extreme temperatures or lack of food.
- **Conclusion:** The pair "Diapause - Zooplankton" is correct.

3. **Analyzing Other Options:**
- **Diapause - Desert Lizard:** Desert lizards do not typically enter diapause; instead, they may exhibit other forms of dormancy or behavioral adaptations to survive in arid environments.
- **Suspend - Locust:** While locusts can undergo phases of swarming and can exhibit behavioral changes, they do not enter a state referred to as "suspend" in the same context as diapause.
- **Conclusion:** Both pairs "Diapause - Desert Lizard" and "Suspend - Locust" are incorrect.

4. **Final Answer:**
- After analyzing all pairs, the only correct match is "Diapause - Zooplankton."
