It is RNA or protein, also given to the expression level of the
gene—a not stable product results in a low expression level. All in all gene
expression is regulated through changes in the number and type of interactions
between molecules
The section of the scientific manuscript that should define young-of-year as sharks less than one year old is the METHODS section. In this section, the features of the subject of study are described.
<h3>Scientific manuscripts and their sections</h3>
A scientific manuscript (commonly known as paper) is a published investigation containing data obtained by using the scientific method.
A case of study is a scientific paper that has a specific format, which is reproduced in different journals publishing this type of investigation.
The main parts of 'A case of study' paper include an Introduction section, Methods section, Results section, Conclusions section and Discussion section (often these last two are combined in a single section).
In the Methods section, the characteristics and properties of the subject of study (in this case, the sandbar sharks) are usually described.

Answer:
Basically, pneumothorax is the presence of free air inside the pleural cavity. Under normal health conditions the parietal pleura and visceral pleura are connected by this space called pleural cavity, which is filled with a fluid called pleural fluid. This fluid is important for preventing friction between the lungs and ribcage and also to link the pleural tissues by a negative pressure (intrapleural pressure) about 5mmHg lower than the alveolar pressure. This pressure difference allows constant opening of the lungs, favoring a satisfactory ventilation.
