Topic content:
The following is a comparison between the A type HINI influenza virus and H5NI avian influenza virus. The correct one is ()
A. Both cause fever in the infected person, so their antibodies are identical
B. The degree of illness caused by infection with different people is generally the same
C. No cell structure, all composed of protein shell and internal genetic material
D. Can live independently and reproduce in large quantities
Best answer:
A、 One antibody can only kill one pathogen, for example, the A HINI antibody can only target the A HINI influenza virus; H5NI avian influenza antibody can only target H5NI avian influenza virus, and their antibodies are different
B、 Type A HINI influenza and H5NI avian influenza are caused by different viruses, and patients generally have different degrees of illness
C、 Type A HINI influenza virus and H5NI avian influenza virus are both viruses. The virus has no cell structure and is composed of protein shell and internal genetic material, which is consistent with the topic
D、 Type A HINI influenza virus and H5NI avian influenza virus are both viruses. They have no cell structure, so they cannot live independently. They can only parasitize in the cells of human beings and other organisms, obtain nutrients from them, and reproduce new viruses. This is not in line with the subject
Therefore: C
Answer analysis:
There is no explanation for this question
