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>
They are called as Noble gases. Hope it helped you. Please mark as the brainliest answer if it helped.
Answer: water potential is the measure of the energy of water to move from one area to another.
Explanation: water potential effects osmosis in a way that water needs to move through membrane and for this movement it requires pressure which makes water potential high so water movement will be faster across the membrane. Water potential determines water movement in osmosis that water move from high water potential region to low water potential region. If water potential is high inside than outside, then water movement to outside will be more.
If water potential is high outside than inside then water will move more inside. If water potential is the same in and outside then water movement inside and outside will be same and this will be called as equilibrium.
