Desert lizards lack the …….A…….ability that mammals have to deal with the ……..B……temperatures of their habitat , but manage to keep their body temperature fairly constant by ………C……..means
Choose the correction for A,B and C

Options

A. A-morphological,B-high,C-behavioural
B. A-physiological,B-high,C-behavioural
C. A-behavioural,B-high,C-physiological
D. A-physiological, B-high,C-morphological

Answer

To solve the question, we need to fill in the blanks A, B, and C with the appropriate terms related to the adaptations of desert lizards compared to mammals.

### Step-by-Step Solution:

1. **Understanding the Context**: The question discusses how desert lizards manage their body temperature in contrast to mammals. It highlights the differences in their abilities to cope with environmental temperatures.

2. **Filling in Blank A**: The first blank (A) requires a term that describes the type of ability that mammals possess but desert lizards lack. Since mammals can regulate their body temperature through physiological processes, the correct term to fill in here is **"physiological"**.

3. **Filling in Blank B**: The second blank (B) needs a term that describes the temperatures of the habitat that both mammals and desert lizards encounter. Since desert environments are typically very hot, the appropriate term for this blank is **"high"**.

4. **Filling in Blank C**: The last blank (C) requires a term that describes how desert lizards manage to keep their body temperature constant. Since they do not have physiological means like mammals, they rely on their behavior to regulate temperature. Therefore, the correct term to fill in here is **"behavioral"**.

5. **Final Sentence Construction**: Putting it all together, the completed sentence reads: "Desert lizards lack the **physiological** ability that mammals have to deal with the **high** temperatures of their habitat, but manage to keep their body temperature fairly constant by **behavioral** means."

### Final Answer:
- A: physiological
- B: high
- C: behavioral
