I dont know about the control but the independent variable is the amount of salt water and the dependent variable is the amount of water and salt rendered.

What are the dependent variable for this question Will water with salt evaporate faster than water without salt?
If you are trying to measure how fast an ice cube melts with or without salt added, your Independent variable would be amount of salt added, and your Dependent variable would be the amount of time it takes to melt.
What is the difference between salt water and regular water?
SALTWATER# Relating to, consisting of, or containing salt water: # Inhabiting or occurring in seawater or salt water: # Done or used in salt water REGULAR WATERsimply the water you are drinking...Salt water contains salt. - Axxo
How do you figure out the variables in a science project?
The variable that you change is the independent variable(which you change). This could be the amount of light, fertilizer or salt that you give to a plant to observe how it affects its growth. What you measure is the dependent variable(the variables that change due to the change in independent variable) eg mass of the plant each day or week, number of leaves or height. All other variables are called the control variables(variables that are constant throughout the experiment). These make the experiment a "fair test". In the above experiment if you were to vary the amount of salt in the soil then each plant must be given the same amount of light, fertilizer, water etc.
How does fresh water become salt water?
Water is already water so when water goes with water it becomes water then you add salt and water and it becomes salt water so you take your salt water and take your water in the water and mix the water in the water with the salt water it becomes the water in the water with salt water

How can mixtures be separated by physical means?
Depends on how it is mixed. If it is (for example) oil and water you can seperate it using a seperating funnel. If water and sand then filtration. If water and salt then evaporation (or you can use distillation if you need both the water and the salt...) If water and something like ethanol then you can use fractional distillation. Or is this not what you mean when you said seperating mixtures by physical means?
How do the cells in a fish react when it moves from freshwater to saltwater?
Salt controls water absorption so the cells would gain water.
Does toys float better on fresh water or on salt water?
No. Toys float better on salt water than on fresh water because salt water has higher density, and the ratio of density controls buoyancy.
What is a variable in which can freeze faster salt or sugar?
If you're trying to set up an experiment, the manipulated variables would be salt and sugar, and varying ratios of salt to water or sugar to water. Say you wanted to find out how fast water froze if it had sugar in it, and wanted to compare it to how quickly it froze with salt. Your controls would be the amount of water, the type of container, and the temperature of the freezer. You could pour 18 plastic cups of water, 6 plain water (the control), 6 with salt and 6 with sugar. You could also vary the amount of sugar or salt in the water (say, .5% to 2.5%, with an increase of .5% in each cup).

Which hormone controls the amount of water in the body?
the minaralocorticoids hormones, which help control the amount of water and salt in the body.
Controls and variables of how to make an egg float?

What are the independent and dependent variables of adding salt water to boiling water?
The quantity of salt added to water is under your control and it will change the boiling point of water,i,e. the temperature of water. So quantity of salt is an independent variable while the temperature of water is dependent variable, when other factors are kept constant.
How do the cells in the fish react when it moves from saltwater to freshwater?
Salt controls water absorption so the cells would gain water.
