Answer:
A deviated septum occurs when bone and the cartilage that divides the nose septum become off-center which results in two unequal nasal septum. This makes one nasal chamber smaller and another larger.
This abnormality causes difficulty in breathing because of the congestion and blockage of the smaller nasal cavity. Due to this congestion airflow in the lungs is hindered which results in lack of oxygen and difficulty in breathing.
Apart from difficulty in breathing it can leads to nose bleeding, loud snoring during sleep, facial pain, headache, and in respiratory infections breathing become more difficult.
A deviated septum can develop due to some trauma or during surgery but some people are born with this abnormality.
Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.
