Multiple Choice

Which of the following statements best describes the difference between artificial selection and natural selection in the context of organic chemistry?

Artificial selection involves human intervention to select desired traits, while natural selection occurs without human influence.

Artificial selection and natural selection both require genetic modification techniques to alter species.

Artificial selection is a process that occurs in nature, while natural selection is controlled by humans.

Artificial selection results in the survival of the fittest, while natural selection leads to the extinction of weaker species.

Verified step by step guidance

Begin by understanding the concepts of artificial selection and natural selection. Artificial selection is a process where humans intentionally select for desirable traits in organisms, often through breeding. Natural selection, on the other hand, is a natural process where organisms with favorable traits are more likely to survive and reproduce.

Consider the role of human intervention in both processes. Artificial selection involves direct human influence, such as choosing specific traits to enhance or propagate. Natural selection occurs without human intervention, driven by environmental pressures and the organism's ability to adapt.

Evaluate the statement that artificial selection requires genetic modification techniques. While genetic modification can be a tool used in artificial selection, it is not a requirement. Traditional methods like selective breeding are also forms of artificial selection.

Analyze the statement that artificial selection is a natural process. This is incorrect because artificial selection is inherently a human-driven process, whereas natural selection is a natural phenomenon occurring in ecosystems.

Reflect on the statement regarding survival and extinction. Both artificial and natural selection can lead to changes in species traits over time, but the concept of 'survival of the fittest' is more closely associated with natural selection, where environmental factors determine which traits are advantageous.
