Hello good afternoon...God bless :) here is the answer to your following question...
Explanation:
Osmosis is important to cells because it allows them to maintain water homeostasis. The most important function of osmosis is stabilising the internal environment of an organism by keeping the water and intercellular fluids levels balanced. In all living organisms, nutrients and minerals make their way to the cells because of osmosis. This obviously is essential to the survival of a cell.
 
        
                    
             
        
        
        
The correct answer is (a) driving.
The pressence of undesirable substances in air is called as air pollution. There are many human activities that contribute to air pollution. The biggest contributor is driving. The pollutants that comes out of the car are carbon dioxide, carbon monoxide. They also release hydrocarbon and nitrogen oxides which when combines in sunlight becomes ozone. Air pollutants emitted by cars and other automobiles increases the level of harmful gases which to severe health problems such as heart disease, asthma, irritation in eyes.
 
        
                    
             
        
        
        
"Inorganic material" is that matter which helps plant to complete the cycle and it's provided by decomposers 'cause they break down dead matters into it.
