This experiment shows that a cell membrane is a of barrier, and is permeable to some substances, but may not be permeable to all substances. What were the independent, dependent, and control variables in your investigation? Describe the variables used in the experiment's part with the eggs. Your answer here: Independent variable / Manipulated variable: Refers to all the variables in an experiment that provoke a response in another variable. This variable is changed during the experiment to analyze how another variable responds to it. Be changes in these variables affect the dependent variable. The researcher can change these variables to see what changes it implies in an object, process, trait, or anything that depends on them. Dependent variable / Responding variable: Its response depends on any change in the independent variable. The dependent variable is the one that is being investigated, studied, and measured. It is a quantity of something which value depends on how the independent variable is changed. It is identified by the letter Y. A change in the dependent variable might be proportional or proportional to the change in the manipulated variable. In the exposed example, the dependent variable is the egg circumference. Constants / Controlled variables: Refers to those variables in an experiment that are controlled and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example, the lid to seal the jar and the amount and concentration of vinegar might be considered as a controlled variable. These elements are used but do not provoke any change in the egg's size.
