Answer:
The correct answer is - option B. ducks and swine.
Explanation:
Influenza virus is capable of the genetic reassortment. This reassortment involves the reassortment of genetic parts in between two influenza strain. This takes place due to the ability of influenza virus to alter or modify the structure of Hemagglutinin (HA) and neuraminidase.
Some other characters also helps them to develop different strains for different host such as mutation, antigenic drift and many other conditions. Influenza virus subtype A are belongs to the avian host so they affect the birds such as duck, swan, gesse. Other than avian variants there is another strain that affect pigs known as swan variants. These strains are virulent if reassorted with human strains.
Thus, the correct answer is - option B.
A. animal can fly; AA. animal can't fly. That should be the correct answer. I hope that this helps you!
The correct answer is all of the above
Answer: English
A eukaryote contains a well-defined nucleus, whereas in prokaryotes, the chromosome lies in the cytoplasm in an area called the nucleoid. In eukaryotic cells, DNA and RNA synthesis occur in a separate compartment from protein synthesis. In prokaryotic cells, both processes occur together.
Explanation: Espanol (Spanish)
Un eucariota contiene un núcleo bien definido, mientras que en los procariotas, el cromosoma se encuentra en el citoplasma en un área llamada nucleoide. En las células eucariotas, la síntesis de ADN y ARN se produce en un compartimento separado de la síntesis de proteínas. En las células procariotas, ambos procesos ocurren juntos.
Answer:
They both had a tail as an embryo, and Their arm and leg structure is similar, but may have a different function.
