Answer:
Hey there!
In an experiment, we have independent and dependent variables. Without them, there wouldn't be an experiment!
The independent variable is the variable that is being changed. For example, in this experiment, the temperature of the salt solution is our independent variable is changing (increasing in this case)
The dependent variable is what changes when the independent variable changes. The change of the dependent variable is always caused by the change in the independent variable. In this experiment, the amount of salt dissolved in water is the dependent variable, because it is changing as the independent variable is changing.
Let me know if this helps :)
Vegetarian is the best choice

Estuaries are areas where fresh water from rivers meets salt water. As the river drains, it carries much nutrient-rich sediment. Many animal species depend on this food source to provide for their young.
