Question

A scientist conducted an experiment to determine the effect of environment on the color of fur 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 black hair allows the rabbit to absorb more heat and keep these extremities warm. the scientist shaved an area of hair on the back of each rabbit, then placed an ice pack over the shaved area on only rabbit
a. the scientists kept the area chilled with an ice pack until the hair had grown back on both rabbit's backs.

Answer 1

The question is incomplete as the figure and question part is missing, however, the figure is attached with the answer and question as follows:

what is the independent variable in this experiment?

What is the hypothesis she is testing?

Rabbit B essential to this experiment?

Answer:

The correct answers are:

The ice (temperature is the variable).

The fur of the Himalayan rabbit changes color with temperature.

Rabbit B is the control group. An experiment without control has no value because the cause of the  change cannot be determined.

Explanation:

In this experiment, the researcher is finding the effect of the temperature on the color of the fur to find this she needs a hypothesis which is The fur of the Himalayan rabbit changes color with a change in the temperature.

To test this she needs to have manipulated the temperature which is the independent variable her and she used the ice to manipulate it so the independent variable is ice. The rabbit B has not got any type of treatment as rabbit A gets so it is the control group that is used to compare it with the experimental group.
