The slow accumulation of genetic changes to an influenza virus over time is referred to as _______.
Ivenika [448]

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>

How does pH impact life processes?
Yakvenalex [24]

Answer:

If a solution has a higher concentration of hydronium ions than pure water, it has a pH lower than 7. A solution with a pH lower than 7 is called an acid. As the hydronium ion concentration increases, the pH value decreases. Therefore, the more acidic a solution is, the lower its pH value is.
