The variables are defined as the factors in an experiment, which are liable to change. The variable can be dependent or independent. The Independent variable is a variable, which is unaffected by the changes in the other variables.

In this case, the brand of the food Shara feeds to the rats is independent factor, but it is changes in the system, so, it is an independent variable.

The effect on the weight of the rat is dependent on the brand of food they are consuming. So, the weight of rats is dependent variable.

Air that enters the pleural space during inspiration but is unable to exit during expiration creates a condition called Pneumothorax.

<h3>What is Pneumothorax?</h3>

An abnormal buildup of air in the pleural space between the lung and the chest wall is known as a pneumothorax. Shortness of breath and quick, acute, one-sided chest discomfort are common symptoms .  A tension pneumothorax happens when an area of injured tissue forms a one-way valve, increasing the amount of air in the gap between the chest wall and the lungs.  As a result, there may be an oxygen deficiency that worsens with time and low blood pressure. Obstructive shock is a type of shock that results from this and can be lethal if left untreated.  A pneumothorax can very infrequently affect both lungs.  Although the term "collapsed lung" can also refer to atelectasis, it is frequently used to describe it.

I'll predict that hydrochloric acid will move fastest across the selectively permeable membrane.

what do you mean by selectively permeable membrane ?

Membranes that are selectively permeable can be described as such. They only allow a few number of molecules and substances to pass. To preserve the internal environment of the cell at a constant or nearly constant level, this is done.

A membrane that is selectively permeable encloses every cell. It serves as a partition between the internal and external environments in addition to enclosing the cellular organelles. It serves as the boundary or fence of the cell. It permits the molecules to move both actively or passively.
