Answer:

These changes probably would have taken place because of antigenic shift or to a smaller extent because of antigenic drift. The antigenic shift takes place when the segments of the influenza viral genome recombine in various ways, and this leads to major modifications to the proteins present on the surface.  

The individuals generally do not possess immunological memory to this novel strain of the virus, thus, the disease that they encounter can be more extreme in comparison to the infection with strains to which they possess certain immunological memory. The antigenic shift can result in influenza pandemics.

Explanation:

<u></u>

<u>-The Retina</u>

<u></u>

The retina is a thin, transparent layer at the periphery of the eye's interior. Light enters the eye and is detected by specialized neural cells. The light is converted into an electrical impulse, by photosensitive rods and cones. This impulse is transmitted and interpreted by the central nervous system or CNS.

Further Explanation:

The nervous system is subdivided into; the central nervous system (CNS), which includes the brain and spinal cord, within the vertebral column; and the peripheral nervous system, which includes nerves that branch into the rest of the body from the brain and spinal cord. Nervous tissue responds to electrical impulses, allowing for communication between different regions of the body.

The peripheral nervous system is further divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system;
