They're two different clotting pathways that use different factors. Though, the intrinsic and extrinsic pathways come together at factor X and eventually result in fibrinogen (factor I) being converted into a fibrin clot by prothrombin (factor II).
Extrinsic begins with factor VII and intrinsic begins with factor XII
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 all have different compositions of protons, neutrons, and electrons. This causes variety and makes atoms different so they can make up different substances
