Answer:
The correct answer is option C) "More than one variable is being tested".
Explanation:
One of the basis of scientific experimentation is to test one variable at the time in order to make sure that the response that is being obtained is the result of that variable and not another one that is not taking into account. In this case, the student is making the mistake of assessing two variables at the same time: the use of detergent and placing the plant in the sun or in the shade. At the end of the experiment the student will not know if the response is the effect of the detergent, the exposure to the sun or a combination of both.

The characteristics of contour lines are:
1. A closed curve shaped contour line;
2. Contour lines are always perpendicular to the flow of water that flows on the surface of the land;
3. Contour lines are always horizontal, not branched, and do not intersect;
4. Contour lines will not be seen if it passes through a building;
5. Contour lines are only designated at a certain height angle;
Explanation:
Contour lines or called tranches, high lines, or horizontal high lines, are imaginary lines in an area or area on the map that connects and shows several points on the map that have the same height. This line further shows the movement or development of the ups and downs of a state of land.
For example, a contour line is indicated by the number + 25 meters, meaning this contour line connects points that have the same elevation angle or height + 25 meters to a certain elevation or height angle.
