which of the following scenarios would evolution by natural selection take place? (1 point)

• Microorganisms reproduce asexually, producing identical offspring
• Penguins reproduce sexually, producing offspring that look different from one another
• Corn is genetically modified and cloned to make identical crops
• A banana tree branch is planted, producing a clone of the parent treb

Evolution by natural selection requires variation among individuals in a population, differential survival, and reproduction based on that variation.

Among the scenarios you provided, the best candidate for evolution by natural selection is:

  • Penguins reproduce sexually, producing offspring that look different from one another.

This scenario involves genetic variation among offspring, which is crucial for natural selection to occur. The other scenarios involve asexual reproduction or cloning, which typically produce identical offspring and do not provide the genetic variation needed for natural selection to act upon.
