Read the following paragraph, then answer the question: A scientist conducted an experiment to determine the effect of environment on the fur color of 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) the other rabbit (B) had nothing placed over the shaved area.

Which Rabbit in the experiment was the control? (A or B)

• Rabbit A (The rabbit with the ice on it's back)

• Rabbit B (The rabbit without the ice on it's back)

What was the independent variable in this experiment?

Read the following paragraph, then answer the question:

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) the other rabbit (B) had nothing placed over the shaved area.

What was the independent variable in this experiment?

• The shaved area on each rabbit's back

• Whether or not the rabbit has an ice pack

• Rabbit A

• Rabbit B

• Type of rabbit

For the following description, select which characteristic of life is being described:

Artic foxes are typically brownish gray in the summer and frosty white in the winter.

• Obtain and use materials and energy

• Maintain stable internal environment

• Respond to their environment

• Made up of cells

• Grow and develop
