Explanation:
The part of the body that responds to the stimulus is called an effector organ. The peripheral nervous system is made up of sensory nerves that transmit impulses from the receptors in sensory organs to the central nervous system and motor nerve that transmits impulses from central nervous system to effector. The central nervous system receives and integrates impulses from the receptors and the relays them to the effector organs.

Answer:
<u>Antigenic drift</u> refers to the slow accumulation of genetic changes to an influenza virus over time.
Explanation:
Antigenic drift is defined as the mechanism by which viruses undergo variation. This mechanism involves the slow accumulation of mutations in the viral genes, that are responsible for coding the antibody binding sites. This leads to the formation of a new strain of virus, which can't be inhibited by the old antibodies. Due to this, the virus can easily spread the disease.
The antigenic drift occurs in the influenza A virus and also the influenza B viruses.
Therefore, <u>Antigenic drift refers to the slow accumulation of genetic changes to an influenza virus over time.</u>
