Considered the following four conditions (A-D) and select the correct pair of them as adaptation to environment in desert lizards. The conditions
(a) Burrowing in soil to escape high temperature
(b)Losing heat rapidly from the body during high temperature
(c)Bask in sun when temperature is low
(d)Insulating body due to thick fatty dermis options

Options

A. (iii),(iv)
B. (i),(iii)
C. (ii),(iv)
D. (i),(ii)

Answer

To solve the question regarding the adaptations of desert lizards, we will analyze each of the four conditions (A-D) provided and determine which pairs correctly represent adaptations to the desert environment.

### Step-by-Step Solution:

1. **Understanding the Environment**:
- Desert lizards live in environments characterized by extreme temperatures: very high during the day and very low at night. They are ectothermic (cold-blooded) and rely on their environment to regulate their body temperature.

2. **Analyzing Condition A**:
- **Condition A**: Burrowing in soil to escape high temperature.
- **Analysis**: This is a valid adaptation. By burrowing, lizards can escape the extreme heat of the desert during the day, helping to maintain a more stable body temperature.

3. **Analyzing Condition B**:
- **Condition B**: Losing heat rapidly from the body during high temperature.
- **Analysis**: This is not a valid adaptation for desert lizards. Rapid heat loss would not be beneficial in a high-temperature environment, as it would lead to a drop in body temperature, making it difficult for the lizard to function.

4. **Analyzing Condition C**:
- **Condition C**: Basking in the sun when temperature is low.
- **Analysis**: This is a valid adaptation. When temperatures drop (like at night), basking in the sun allows lizards to absorb heat and raise their body temperature, which is crucial for their metabolic processes.

5. **Analyzing Condition D**:
- **Condition D**: Insulating body due to thick fatty dermis.
- **Analysis**: This is not a valid adaptation for desert lizards. They do not have a thick fatty dermis; instead, their skin is dry and rough, which helps minimize water loss rather than provide insulation.

6. **Selecting the Correct Pair**:
- The correct adaptations based on the analysis are:
- Condition A (Burrowing in soil to escape high temperature)
- Condition C (Basking in sun when temperature is low)
- Therefore, the correct pair is A and C.

### Final Answer:
The correct answer is the pair (A and C).
