Answer:
When a pig is simultaneously infected with an avian influenza strain and a human influenza strain, the two sets of genes present in the pig result in antigenic shift (option b).
Explanation:
Antigenic shift occurs when two different strains of a virus meet in an organism and combine to produce a new type of virus containing a mixture of the surface antigens of the strains that have combined.
Once two virus of different strains coexist in an organism they lose their viral capsid, exposing the genetic information that will be transcribed in the host cell into a different virus, containing the combination of the surface antigens of the viruses that were found in the mentioned organism.
<em>The other options are not correct because mainly </em><em><u>genetic drift</u></em><em> refers to changes in the antigens of a virus due to repeated random mutations in the viral genome.</em>
This would be known as Pica. Generally pica affects young children, and sometimes, interestingly, affects pregnant women. People with pica have strange cravings for non edible things. This is, understandably, are rare disorder.
Hope this helped! It's a really interesting thing to learn about and I suggest you do more research just for the curiosity of it.

If you don't use proper body alignment when working out your bones can shift and easily brake. When most people work out they do not use proper alignment therefore they have shoulder, knee, back, and hip problems. If you lift a weight and your body is not aligned you may have problems in the future some you may not be able to be fixed. Therefore it is important to have your body in alignment when you work out or any heavy lifting.<span />
