Answers
GPT 3.5
1. What is natural selection?
a. The process by which individuals better adapted to their environment survive and reproduce
b. The process by which individuals with the most offspring survive and reproduce
c. The process by which individuals randomly survive and reproduce
d. The process by which individuals with the most resources survive and reproduce
2. What is an adaptation?
a. A trait that helps an organism survive and reproduce in its environment
b. A trait that is harmful to an organism in its environment
c. A trait that has no effect on an organism's survival and reproduction
d. A trait that is inherited from previous generations
3. True or False: Natural selection always results in the evolution of new species.
a. True
b. False
4. Which of the following is an example of natural selection?
a. A farmer breeding cows with the biggest horns
b. A gardener selecting the tallest flowers to plant in their garden
c. A predator selecting the slowest prey to catch
d. A population of birds with thicker beaks surviving a drought and passing on their genes
5. What is the role of genetic variation in natural selection?
a. Genetic variation has no effect on natural selection
b. Genetic variation allows for the survival of a population in changing environments
c. Genetic variation decreases the chances of survival in a population
d. Genetic variation ensures that all individuals in a population have the same traits
6. How does natural selection contribute to the process of evolution?
a. Natural selection causes random mutations in a population
b. Natural selection leads to the extinction of species
c. Natural selection results in the adaptation of a population to its environment over time
d. Natural selection has no effect on the evolution of species
7. Give an example of natural selection in action in the natural world. Explain how the process of natural selection is evident in this example.
8. How does artificial selection differ from natural selection? Give an example of artificial selection and explain how it differs from natural selection.
9. How can the concept of natural selection be applied to human societies and cultures?
10. Why is understanding natural selection important for fields such as medicine, agriculture, and conservation?
Answer Key:
1. a. The process by which individuals better adapted to their environment survive and reproduce
2. a. A trait that helps an organism survive and reproduce in its environment
3. b. False
4. d. A population of birds with thicker beaks surviving a drought and passing on their genes
5. b. Genetic variation allows for the survival of a population in changing environments
