Answer:
The consumption of alcohol or alcohol flavoring.
Explanation:
In research, we usually have two different types of variables:
- The independent variable is the one that the researchers can control and that will have an effect on another variable.
- The dependent variable is the one that cannot be control and that is affected by the independent variable. Researchers observe this variable to see how it changes. This is the variable that will be tested or measured.
In this example researchers told some subjects they were receiving alcohol and to some others they were not receiving alcohol and measured their physical coordination and mental capacities. We can see that the researchers could control the amount of alcohol the participants were going to consume and the coordination and mental capacities would be affected by this consumption. Therefore, since <u>the consumption of alcohol </u><u>will have an effect on the other variable</u>, this would be the independent variable.

<u>Answer:</u>
<em>Earthworms are very sensitive towards the odor. </em>
They use it for locating the food in the soil. Because earthworms are dependent upon microorganism in the soil, they must be sensible for the <em>presence of any food around them if they do not respond the odor then they may die. </em>
Earthworms have the escape response so they quickly respond the external stimuli at the part they are stimulated. <em>With the increasing frequency of stimuli at the same part they slowly decrese the response towards it.</em>
