After reading the paragraphs below, answer the questions that follow.

Introduced species are a problem all over the world, and there are many examples in the United States. Several years ago, a fisherman caught a northern snakehead fish in a pond in Crofton, Maryland (a suburb of Washington, DC). It was suspected that the fish in the Crofton pond were purchased locally and then intentionally released. Snakeheads are top predators, and 90% of the northern snakeheads' diet consists of other fishes. The northern snakehead can breathe out of water and travel short distances (about 100 feet) across land. They also breed rapidly. Females can lay more than 100,000 eggs per year. Juveniles have also been identified in the Potomac River and other rivers in Pennsylvania.


Based on the characteristics of the snakehead described, which strategy is most likely to reduce the spread of this species significantly?
◦ introducing algae and photosynthetic bacteria to reduce nutrient levels in the water
◦ introducing a natural predator to feed on juvenile snakeheads
◦ capturing breeding snakeheads and sterilizing them so that they cannot breed any longer
◦ extending the fishing season for prey fishes

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
