When the body cannot regenerate tissue or cells after they have been destroyed, it makes scar tissue instead. The purpose of the scar tissue is to restore:

A. The fecal-oral route is associated with gastrointestinal viruses, not respiratory infections like influenza.

B. While influenza can spread through airborne transmission, it primarily spreads via respiratory droplets, which are larger and do not remain suspended in the air for long distances.

C. Direct contact can also transmit the virus, but it is less common compared to the droplet route.

D. Respiratory droplets are the primary mode of transmission for influenza, occurring when an infected person coughs or sneezes, releasing droplets that can be inhaled by others nearby.

A. Hypertrophy refers to the increase in the size of cells, leading to an increase in the size of the organ or tissue, which is evident during pregnancy as the uterus enlarges.

B. Atrophy involves a decrease in cell size, leading to a reduction in tissue mass, which is not applicable to pregnancy.

C. Metaplasia is a process where one differentiated cell type is replaced by another, typically in response to chronic irritation or inflammation, not seen in normal pregnancy.

D. Dysplasia refers to abnormal development of cells, which is not a characteristic of a normal physiological process like pregnancy.
