The inferior most, or the lowest, sinus cavity is called the maxillary sinus. It is also the largest sinus cavity and it drains into the middle of the nose. The maxillary sinus is located above the upper jaw and is easily visible on x-rays above the premolar and the molar teeth. 
The symptoms of sinusitis include headaches near the sinus and discharge of foul-smelling mucus.
        
             
        
        
        
Answer: Both Respiration and Burning uses oxygen. Both Respiration and Burning produces energy. Both Respiration and Burning gives out carbon dioxide as the end product.

The process of photosynthesis is the synthesis of food molecules from inorganic compounds using energy from sunlight. 
<h3>WHAT IS PHOTOSYNTHESIS?</h3>
Photosynthesis is the process whereby green plants obtain their food (glucose) in the presence of sunlight as an energy source. 
Photosynthesis takes place in two stages namely;
- Light dependent reactions
- Light independent reactions
Photosynthesis combines carbon dioxide and water as reactants as follows:
6CO2 + 6H2O = C6H12O6 + 6O2
Therefore, the process of photosynthesis is the synthesis of food molecules from inorganic compounds using energy from sunlight.
