Factors Affecting Biological Diversity Answers

A population of snakes that eat small rodents enters a new habitat. In the new habitat, there are many species of rodents, and their populations are high because there are few natural predators. What will most likely be the effect on the genetic variation of the snake population?

In a population of seals, most of the seals have similar coloring. However, one seal has albinism. This seal is white and is almost completely blind. What is most likely the cause of this difference from the rest of the population?

Which environmental factor could lead to a decrease in genetic variation in a population of tuna?

In Wisconsin, a very large population of lake trout, in which individuals mate at random, experiences no migration, mutations, nor selective pressure for a number of years. Which of these is most likely to occur in the population?

Environmental factors can influence natural selection because they can increase or decrease

A group of students is walking in the park, and one of them takes a picture of a pollen grain that is being blown by the wind. What caption can the student use for this picture?

A new pesticide has been introduced to the habitat of this population of beetles.Which describes the effect of this environmental change?

Which term best describes the difference in colors of the birds below?

A high population of greater prairie chickens once inhabited the prairies of Illinois. The conversion of the prairies into agricultural land caused the chickens to lose their habitat. Studies have concluded that this change greatly reduced the greater prairie chicken population. The habitat loss also resulted in a decrease in the population’s genetic variation.Which change in the gene pool occurred in the greater prairie chicken population?

A scientist has been tracking and studying a population of deer in Yellowstone National Park. He surveys the population every six months. Usually, the population is thriving and has a gene pool with a wide variety of traits. But during one six-month period, an event occurred that affected the population, and when the scientist returned, the amount of genetic variation had decreased significantly. Which of the following is most likely the event that occurred to change the population?
