An asymptomatic carrier
Explanation:
An asymptomatic carrier (healthy carrier or just carrier) is a person or other organism that has become infected with a pathogen, but that displays no signs or symptoms.
Although unaffected by the pathogen, carriers can transmit it to others or develop symptoms in later stages of the disease. Asymptomatic carriers play a critical role in the transmission of common infectious diseases such as typhoid, C. difficile, influenzas, and HIV. While the mechanism of disease-carrying is still unknown, researchers have made progress towards understanding how certain pathogens can remain dormant in a human for a period of time. A better understanding of asymptomatic disease carriers is crucial to the fields of medicine and public health as they work towards mitigating the spread of common infectious diseases.
They are combined because both professions pay a lot of money and both help to serve people.
Answer:
The correct answer is option C. ear.
Explanation:
A myringotomy is a surgery in which a very small incision is made in the tympanic membrane or eardrum of the ear by the surgeon to release pressure created by excessive fluid, or to remove pus from the middle ear.
The surgeon uses the myringotomy knife to create an incision in the tympanic membrane. The myringotomy knife is a needle-like a lancet blade which helps in piercing and incision.
Thus, the correct answer is option C. ear.
