Answer:

c. The dependent variable is the plant heights; the independent variable is the room temperature

Explanation:

Here, the effect of room temperature on the height of plants is being studied. The amount of light the plants get is equal the only differentiating factor is the room temperature.

In an experiment to determine the inter relationship between two variables on variable is changed and the variable which changes with respect to the first variable is studied.

The variable which is changed inpendently i.e., it does not change with respect to another variable is called the independent variable.

The variable which changes with respect to the independent variable is called the dependent variable.

Hence, the plant height is the dependent variable and the room temperature is the independent variable.

Karolina [17]
On June 27, 1950, President Harry S. Truman announces that he is ordering U.S. air and naval forces to South Korea to aid the democratic nation in repulsing an invasion by communist North Korea. The United States was undertaking the major military operation, he explained, to enforce a United Nations resolution calling for an end to hostilities, and to stem the spread of communism in Asia. In addition to ordering U.S. forces to Korea, Truman also deployed the U.S. 7th Fleet to Formosa (Taiwan) to guard against invasion by communist China and ordered an acceleration of military aid to French forces fighting communist guerrillas in Vietnam.
