Question

certain types of influenza virus originate in an_____host, like a bird. the avian influenza virus may typically infect and transmit the virus among____animal species at a time. in some instances, an____host, like a pig, allows for the exchange of____between two different strains of the influenza virus: an avian influenza strain and a human virus strain. the exchange of genetic material allows the influenza virus to______into a new form. the virus can now be transmitted to a____host, such as humans, and spread easily from person to person causing a flu outbreak.

Answer 1

Answer: animal, one, intermediate, genetic material, evolve, new

Step-by-step explanation:

certain types of influenza virus originate in an animal host, like a bird. (influenza A can circulate in birds, passing it to other animal species)

the avian influenza virus may typically infect and transmit the virus among one animal species at a time. (subtypes of birds can cross into and infect other species)

in some instances, an intermediate host, like a pig, allows for the exchange of genetic material between two different strains of the influenza virus: an avian influenza strain and a human virus strain. (often, the same influenza that infects humans can also be found to infect swines)

the exchange of genetic material allows the influenza virus to evolve into a new form.

the virus can now be transmitted to a new host, such as humans, and spread easily from person to person causing a flu outbreak.
