Answer:
amount of copper
Explanation:
<em>The independent variable would be the amount of copper fed into the experimental rats.</em>
An independent variable during an experiment is a variable whose value is not dependent on any other variable being measured in the experiment.
The value of an independent variable is not changed by any other variable in an experiment. In actual fact, the effect of the independent variable is being tested on other variables (dependent variables) in the experiment.
<u>Hence, in an experimental study of the effect of copper deficiency on coat color in rats, the amount of copper fed into the system of the rats will be varied and the effects of this variation on the coat color of the rats would be observed by measuring relevant variables. Therefore, the amount of copper is the independent variable.</u>
Answer:
Fault zones cause Earthquakes
causes the shaking that is associated with earthquakes
Explanation:
An Earthquake takes place whenever the underground rocks break in the fault zone suddenly. While they break they release an energy that generates seismic waves causing the shake of the Earth ground.
While the rocks get rubbed against each other it sticks and creates pressure, this pressure breaks the rocks and Earthquake take place. The rocks break in the focus zone of the Earthquake and the shaking is caused by the fault zone.
