Variation
Variations can lead to either an increase or decrease in fitness
Phenotype
The light-colored moths are the most common due to antipollution regulations
A mouse that needs less water
Ability to survive with less food
If there are a wide variety of traits in a population, it is more Likely that some individuals will be able to survive and reproduce
Reasoning
The curve becomes narrower and taller
Raising chickens and having larger ones reproduce in order to produce more meat

1. Variation can lead to either an increase or decrease in fitness.
2. Phenotype: The light-colored moths are the most common due to antipollution regulations.
3. A mouse that needs less water: An adaptive trait that can increase the survival chances of that mouse.
4. Ability to survive with less food: An adaptive trait that can increase survival chances.
5. If there are a wide variety of traits in a population, it is more likely that some individuals will be able to survive and reproduce.
6. Reasoning is the term that means making sense of information.
7. The curve becomes narrower and taller: Refers to a situation where the distribution of a trait becomes more uniform in a population, rather than being spread out over a wide range.
8. Raising chickens and having larger ones reproduce in order to produce more meat: A common agricultural practice aimed at improving desired traits in a population.
