Answer and Explanation:
During an experiment, data from an experimental group are compared with the data of a control group. These two groups are identical in all aspects except for the independent variable that the researcher changes in the experimental group to observe how they affect the individuals. This variable keeps constant in the control group.
- The experimental group is the one that receives the experimental procedure, with changes in the independent variable. There can be several experimental groups. In the exposed example, the experimental groups are the different types of food.
- In the control group, the variable measured keeps constant, not influencing the results. This isolates the effect of the independent variable on the experiment and helps to find alternative explanations to the different results. The control group corresponds to the normal dry food.
- Manipulated variable: Refers to all the variables in an experiment that provoke a response in another variable. They are also known as independent variables. The researcher can change these variables to see what changes it implies in an object, process, trait, or anything that depends on them. In the exposed example, the researcher manipulates the type of food he gives to the cat.
- Responding variable: Refers to the dependant variable, which response depends on any change in the independent variable. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. In the exposed example, the dependent variable is the response of the cat to the change of food.

Do u have answer choices with this question?
Answer:
<h2><em><u>True</u></em><em><u> </u></em></h2>
Explanation:
<u>It's</u><u> </u><u>a</u><u> </u><u>true</u><u> </u><u>statement</u><u> </u><u>as</u><u>,</u>
- When we inhale the diaphragm moves downwards and the rib cage moves upwards and outwards to let enter the outside air containing oxygen come in.
- While we exhale the diaphragm comes to its position and the rib cage move downwards and inwards to let out the inside carbon-dioxide and other games out.
<u>Hence</u><u>,</u><u> </u><u>we</u><u> </u><u>can</u><u> </u><u>conclude that</u><u> </u><u>breathing involves the movement of diaphragm and Rib cage</u><u>.</u>
