Final answer:
When environmental conditions change, variation among the members of a species increases the likelihood of survival and successful reproduction. Sexual reproduction generates genetic diversity, which enhances a population's ability to adapt to a changing environment. The correct option is c) The species requires very specific environmental conditions.
Step-by-step explanation:
When environmental conditions change, it is more likely that at least some members of a species will survive if there is variation among the members. This variation allows some individuals to be better suited to the new conditions, increasing their chances of survival and successful reproduction. In sexually reproducing species, this variation is achieved through the combination of genetic material from two individuals, resulting in offspring with diverse phenotypes.
The genetic diversity provided by sexual reproduction gives species a better chance of surviving in a changing environment. On the other hand, asexually reproducing species, where the members are genetically identical, have less variation and may struggle to adapt to new environmental conditions.
The correct option is c) The species requires very specific environmental conditions.
