Answer 1

1. C 2. B 3. C

Answer 2

## Step1 The first question is about the concept of natural selection and its impact on the fitness of an organism. Natural selection is a process where organisms that are better adapted to their environment tend to survive and produce more offspring. The options provided are all potential outcomes of natural selection, but the one that best encapsulates the overall goal of natural selection is the ability to survive, find a mate, and produce offspring. ## Step2 The second question is about the concept of genetic inheritance and how it can lead to physical changes in organisms. The green anoles are known for their ability to change their skin color rapidly in response to various stimuli. This is a trait that is passed down from parents to offspring, which is why option B is the correct answer. ## Step3 The third question is about the concept of natural selection and how it can lead to physical changes in organisms. The blue flying fish have enlarged pectoral fins that allow them to glide above the ocean surface. This is a trait that has likely evolved over time due to the survival advantage it provides, which is why option C is the correct answer.
