Question

The survival of a species depends on its ability to adapt to changes in the environment. A species must be capable of surviving and reproducing despite changes to food sources, climate, or threats from predators. Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment?
Mutations are the cause of disease in the species.
Mutations are a source of variation in the species.
Mutations are always passed on to subsequent generations of the species.
Mutations are not harmful when they occur in somatic cells of the species.

Answer 1

The statement that correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment is:

**Mutations are a source of variation in the species.**

This statement highlights that mutations introduce genetic diversity within a population, which can provide the basis for adaptation to environmental changes. Variability in traits can lead to some individuals being better suited to survive and reproduce under new conditions, thereby enhancing the overall survival of the species.
