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>

Explanation:
Past observations made early in history as well as telescopes and space probes are very important in studying our universe and galaxies.
- Space probes are increasingly gaining momentum as technological and scientific advancements are being made.
- Telescopes are used to see or picture objects that are very far away in space.
- Also, understanding the past records and historical data is essential for the study of the universe.
Microscopes are not used in galactic studies. They are only used to study the world of micro-organisms.
