Detailed explanation-1: -Mutations increase the likelihood that a species will survive in a changing environment by providing new genetic information that can help the species survive and reproduce.
Detailed explanation-2: -An adaptation is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment.
Detailed explanation-3: -Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment? Mutations are a source of variation in the species.
Detailed explanation-4: -In nature, these resources are often limited, and individuals within a population must compete for resources in order to survive. Long-term survival of a species is based on obtaining resources that are limited, so that individuals can live and reproduce.
Detailed explanation-5: -In natural selection, genetic mutations that are beneficial to an individual’s survival are passed on through reproduction. This results in a new generation of organisms that are more likely to survive to reproduce.
