Detailed explanation-1: -Plant height is the dependent variable that responds to the change in the independent variable. Each plant is exposed to an equal amount of sunlight, so sunlight is the control variable.
Detailed explanation-2: -VARIABLES: The independent variable is the different amounts salt that will be added to the water (what is done by the scientist). The dependent variable is the boiling temperature of the water (what is being measured). III: HYPOTHESIS: If salt is added to water then, the boiling temperature is lowered.
Detailed explanation-3: -Salts in the soil can absorb water. This results in less water being available for uptake by the plants, increasing water stress and root dehydration. This is referred to as physiological drought, which, if not corrected, can lead to reduced plant growth.
