A fox with thick fur would have a survival advantage over other foxes
Emily H.
The arctic fox is uniquely adapted to its environment with white fur for camouflage, a small nose and ears and warm coat to prevent heat loss and strong paws for running and hunting. Which statement best describes how the arctic fox population may have adapted to its environment over time? Choose the correct answer. Foxes were bred to meet human needs for white fur. Foxes developed smaller ears and noses in response to their cold climate. They were able to survive and pass this trait on to their offspring. Foxes changed their fur to white to hide from predators and disguise themselves from their prey. They were able to survive and pass this trait on to their offspring. Variation existed in the traits of the fox population. Foxes with smaller ears and noses were able to stay warmer and were more likely to survive and reproduce to pass their genes on to offspring. Over time, the fox population showed a shift to smaller ears and noses.

The arctic fox has adapted to its environment in a number of ways. Its fur turns white in winter and it does not begin to shiver until temperatures plunge below 10 degrees Fahrenheit. Global warming is likely to bring many changes, including an increase in mean air temperature. Over time, the arctic fox will have to adapt to this change. Which adaptation is MOST LIKELY to occur? A) Its paw pads may thicken. B) Its fur may stay white longer. C) Its tail may have thinner fur. D) Its ears may be shorter and rounder.
