Explanation:
An organic compound is one which has at least one carbon atom that is bonded to several other atoms (may be metallic or non metallic) by a single or double bond is termed as organic compound . The most common atoms with which carbon forms bond are hydrogen, nitrogen,and oxygen.
Some common examples are -
Methane -

Answer:
The maxillary sinus, that is, the sinus located in the upper jaw, would be affected.
Explanation:
Sinusitis is a very traditional disease that is associated with headache, discomfort, and increased mucus making.
The causes can be viral or bacterial or even by some inhaled noxa, sinusitis of this type is bilateral, different from sinusitis of dental cause that are usually unilateral.
The paranasal sinuses are the sinuses that pneumatize the head, that is, they generate an internal air current in the bones to be able to heat and disinfect them from those noxas that are inhaled (that is why they are covered by a ciliated mucosa that drags the noxa to the outside and also its structure is pseostratified with mucous cells that secrete mucus enveloping the noxa).
Another function of the paranasal sinuses is to be able to alleviate the weight of the head, since the shell and the bones that remain in the head formation are very heavy, thus generating these cavities filled with air to alleviate the feeling of "heavy head" "When they become inflamed and filled with mucus, they are obliterated or with a reduced space, so the head feels heavier for some people.
The paranasal sinuses are the maxillary sinuses that are in the upper jaw, the sphenoid sinuses that are in the sphenoid, the ethmoid sinuses that are in the ethmoid and the frontal ones that are in the frontal bone that is vulgarly called as the forehead.

The result shows that the microorganism is Staphylococcus aureus.
<h3>How to explain the microorganism?</h3>
Blood Agar media shows colonies which means the microbe must be a fastidious one. It allows bacteria to be distinguished by the type of hemolysis they produce. Here in the image, beta hemolysis is depicted.
Gram staining depicts a gram-positive coccus. Gram-positive organisms take up crystal violet dye and are stained purple while gram-negative organisms take up the safranin dye and give pink to red colonies.
Catalase protects the organisms from reactive oxygen species and Coagulase. According to the above results, the microorganism is Staphylococcus aureus.
