The environmental factor that could lead to a decrease in genetic variation in a population of tune is an increase in pollution. The option that only shows an environmental factor is pollution. The effect of pollution on the population of fish is that it leads to some damaging effects that affects the life cycle of the fish.

The burrowing owl is found in dry, open areas such as grasslands, prairies, savannas, deserts, farmlands, golf courses, and other urban areas throughout most of western United States and Florida, Central America, and most of South America. It makes its home in burrows of other animals and primarily eats insects and small rodents. As humans build more cities, nearby burrowing owl habitats change due to destruction of burrows and loss of prey. Which is the least likely outcome of the habitat changes that are described? The niche of the burrowing owl may change as it adapts to the changes. The niche of the burrowing owl may change as it moves to a new habitat. The population of the burrowing owl may be reduced or even become extinct. The population of the burrowing owl may increase in its new surroundings.

Two animals that can be found at the Grand Canyon include the Abert’s and Kaibab squirrels. The Abert’s squirrel is found at the south rim of the canyon and in a few surrounding states. The Kaibab squirrel, however, can only be found at the canyon’s north rim, mainly on the Kaibab Plateau. The Kaibab squirrel is not found anywhere else in the world. Scientists believe that the squirrels are actually closely related and have developed separately as a result of geographic isolation. It is possible that the squirrels were separated by plateau erosion that separated the forests and isolated the Kaibab population. Some scientists are studying if the squirrels are now two separate species or if the Kaibab squirrel is simply a subspecies of the Abert’s squirrel. Separate species are unable to reproduce with each other. Which evidence would be used to support the claim that the squirrels are two separate species?
