Abies, lizards and polar bear can tolerate (a) Wide range of temperature (b) Only a narrow range of temperature (c) Wide range of salinities

Options

A. (a) & (b)
B. (b) & (c)
C. (b) only
D. (a) & (c)

Answer

To solve the question regarding the tolerance of Abies (a genus of trees), lizards, and polar bears, we need to analyze the options provided:

1. **Understanding the Organisms:**
- **Abies:** These are coniferous trees, commonly known as fir trees. They are found in a variety of climates, from cold mountainous regions to temperate forests.
- **Lizards:** These are reptiles that can be found in diverse habitats, including deserts, forests, and grasslands. Their ability to tolerate temperature varies by species, but many can adapt to a wide range of temperatures.
- **Polar Bears:** These mammals are adapted to live in extremely cold environments, particularly in the Arctic. They are well-suited to tolerate cold temperatures but can also withstand some variation in temperature.

2. **Analyzing the Options:**
- **(a) Wide range of temperature:** Given that Abies can grow in various climates, lizards can adapt to different temperatures, and polar bears can endure cold but also some temperature changes, this option seems plausible.
- **(b) Only a narrow range of temperature:** This option does not fit well since all three organisms are known to tolerate a range of temperatures.
- **(c) Wide range of salinities:** While some organisms can tolerate varying salinities, this is not a characteristic of Abies, lizards, or polar bears. They are not typically associated with environments where salinity is a major factor.

3. **Conclusion:**
- The best choice is **(a) Wide range of temperature** because all three organisms can tolerate varying temperatures, although their specific tolerances differ.

### Final Answer:
**(a) Wide range of temperature**
