Answer:
The virus that is correctly matched with its structure is HIV - helical shape.
Step-by-step explanation:
HIV (Human Immunodeficiency Virus) is a retrovirus that contains RNA as its genetic material. Its structure is characterized by a long, cylindrical shape with a helical symmetry. The virus is surrounded by an envelope containing glycoproteins that help it to attach to and enter host cells. Inside the envelope, the virus contains a capsid, which is made up of many copies of the viral protein p24, and the RNA genome. Polio virus, on the other hand, is correctly matched with a polyhedral shape. Polio virus is a small, non-enveloped virus with a roughly spherical shape and icosahedral symmetry. Ebola virus is correctly matched with a complex shape. Ebola virus is a filamentous, enveloped virus with a helical symmetry. The virus is named after the Ebola River in the Democratic Republic of the Congo, where it was first identified in 1976. Bacteriophage is correctly matched with an enveloped shape. Bacteriophages are viruses that infect bacteria and are characterized by an icosahedral head and a tail composed of a helical sheath and a base plate. Some bacteriophages also have an envelope surrounding their capsid, which is derived from the host cell membrane during the process of viral assembly and release.
