What is defined as an inherited characteristic that increases an organism's chance of survival?

• A. Mutation
• B. Adaptation
• C. Specification
• D. Natural selection

Answer: (B)

The correct choice is adaptation, which refers to an inherited trait that enhances an organism's ability to survive and reproduce in its specific environment. Adaptations can take many forms, including physical traits, behaviors, and physiological processes that have evolved over time as a result of environmental pressures. For example, the thick fur of polar bears is an adaptation that helps them survive in cold climates by providing insulation against the low temperatures.

In comparison, mutation refers to a change in the DNA sequence, which can introduce new traits but does not directly relate to the fitness benefits of those traits unless they provide a survival advantage. Specification, on the other hand, pertains to the process by which new species arise and is not inherently linked to survival characteristics. Natural selection is the mechanism through which adaptive traits become more common in a population over generations, but it is not itself defined as a characteristic. Instead, it describes the process that drives the prevalence of adaptations within populations over time.
