Consider the following scenario:
There are variations in the fur color of mice. Some mice have white fur. Some have dark fur. Foxes more easily catch mice with white fur.

Here are the correct responses to each of your questions regarding natural selection:
1. **Natural selection causes changes in:**
- **Populations.**
- Natural selection acts on individuals but results in changes in the population over time.
2. **Which statement is accurate about natural selection?**
- **Natural selection does not change the alleles an organism has.**
- Natural selection does not change the alleles, but it favors certain alleles over others based on their effects on survival and reproduction.
3. **Which mutation scenario will always lead to natural selection?**
- **A mutation causes a specific advantage within the population.**
- This is the only scenario that guarantees that the mutation will be favored by natural selection.
4. **Consider the following scenario:**
- **Brown fur will become predominant.**
- Since foxes catch white-furred mice more easily, those mice are less likely to survive and reproduce, leading to brown fur becoming more common over time.
5. **What evolves during natural selection?**
- **The proportion of different traits in a population.**
- Natural selection leads to changes in the frequency of traits (and the alleles associated with those traits) in a population over generations.
These answers summarize how natural selection influences populations and traits over time.
