Using Science Skills

Use the diagram below to answer the following questions on the lines provided.

A scientist conducted an experiment to determine the effect of environment on the fur color of a Himalayan rabbit. The Himalayan rabbit typically has a white coat except for its colder nose, feet, tail, and ears, which are black. The scientist shaved an area of hair on the back of each rabbit, then placed an ice pack over the shaved area on one rabbit (A).
