Question

using science skills 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 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). figure 1 - 1 25. interpreting graphics in figure 1 - 1, which rabbit is the control? a. rabbit a c. rabbit c b. rabbit b d. they are all variables 26. interpreting graphics in figure 1 - 1, what is the independent variable in this experiment? a. rabbit b c. the ice b. rabbit c d. they are all controls 27. formulating hypotheses before completing the experiment in figure 1 - 1, the scientist made a hypothesis. what is the hypothesis she is testing? if the ________ is ______ then the ______ will ________. 28. applying concepts why is rabbit b essential to this experiment?

Explanation:

1. In an experiment, the control is the group not exposed to the experimental variable. Rabbit B has no ice - pack, so it is the control.
2. The independent variable is the factor that is changed or manipulated in an experiment. Here, the ice (temperature change) is being manipulated, so the ice is the independent variable.
3. The hypothesis is likely about the relationship between temperature and fur color. If the temperature is cold, then the fur will change color.
4. Rabbit B is essential as it serves as a control. It provides a baseline to compare the effects of the ice - pack (temperature change) on Rabbit A. By having a control, we can determine if the change in fur color on Rabbit A is due to the ice - pack or other factors.

Answer:

1. B. Rabbit B
2. C. The Ice
3. If the temperature is cold, then the fur will change color.
4. Rabbit B serves as a control, providing a baseline for comparison to determine if the change in fur color on Rabbit A is due to the ice - pack.
