Question

natural selection causes changes in

populations
individuals
genotypes
phenotypes

which statement is accurate about natural selection
natural selection cannot inactivate genes
natural selection cannot occur through mutations
natural selection does not impact reproduction rates
natural selection does not change the alleles an organism has

which mutation scenario always lead to natural selection
a mutation causes an inactivated gene to be reactivated
a mutation causes a specific advantage within the population
a mutation causes a gene to become inactivated
a mutation causes a specific variation within the population

there are variations and the fur color of some mice have white fur some have dark fur foxes, more easily catch mice with white fur

what will likely be a consequence of the scenario?

mice with brown fur will be less likely to pass on their genetic information
brown fur will become predominant
mice with white fur will be more likely to survive and reproduce
white fur will become predominant

what evolves during natural selection

inactivated genes
entire species
the phenotypes of individual organisms
the proportion of different treats in a population

1. **Natural selection causes changes in:**
- **Populations**
(Natural selection acts on individuals, but it is populations that evolve over time.)

2. **Which statement is accurate about natural selection:**
- **Natural selection cannot inactivate genes**
(Natural selection operates on existing variations and phenotypes but does not directly affect or inactivate genes themselves.)

3. **Which mutation scenario always leads to natural selection:**
- **A mutation causes a specific advantage within the population**
(Natural selection acts on advantageous mutations that increase an organism's fitness within its environment.)

4. **There are variations and the fur color of some mice have white fur and some have dark fur. Foxes more easily catch mice with white fur. What will likely be a consequence of the scenario?**
- **Mice with white fur will be more likely to survive and reproduce.**
(In this scenario, white-furred mice are more susceptible to predation, so dark-furred mice are more likely to survive and reproduce.)

5. **What evolves during natural selection?**
- **The proportion of different traits in a population**
(Natural selection leads to changes in the frequency of traits within a population over successive generations.)
