<u>Smoking</u> causes respiratory disorders such as bronchitis, pneumonia and lung cancer.
<u>Explanation:</u>
Respiratory disorders such as bronchitis, pneumonia and lung cancers are caused by smoking tobacco, air pollution and by infection. Smoking is the predominant cause of this respiratory order it also raises the level of air pollution which becomes hazardous to all the living organisms.
Infection in the lungs which is identified as pus in air sacs and found as inflamed lungs is usually life threatening. Severe shortness of breathe called the bronchitis is due to airborne chemicals.
 
        
             
        
        
        
Answer:
Sensory transduction
Explanation:
The sensory process involves many steps to send the signals from the receptor to the brain.
In this, the step that is involved in the conversion of the physical energy into the electrical signal at the sensory receptor  (in the given case mechanoreceptors) is known as the Sensory transduction.
When the mechanoreceptors get stimulus by the physical force, it opens the mechanical gate of the dendrites which allows the influx of the positive ions. The influx of the positive ions causes depolarization of the membrane which initiates the action potential which is then transmitted to the brain.
Thus,  Sensory transduction is the correct answer.
 
        
                    
             
        
        
        
This is extremely vague, but assuming this is regarding concentration gradient in the nervous system, the Sodium-Potassium pump is responsible for transporting sodium and potassium.
